If you're using Windows 7, do this: Start -> Configuration -> Clock, Language and Region -> Change Location - and change it to the United States. '' -> '' -> '' -> Formats - and change all decimals to dots.

Yes!!!! Thank you! You just saved me from emotional eating! THANK YOU!!!! And firehawk44, thank you too! Thanks everyone! Everything's working fine now!!

Can you make a step by step guide one how to change your language settings in Windows 7? I don't want to make mistakes, you know.

Tried it, nothing changed. Good guess though.

I don't use anything else very much on my computer. FSX and Google Chrome are the basics for my computer actually. I don't have a problem with fully restoring my computer, because it was already getting kinda slow and stuff. I think it's a good idea to have a new, fresh start.

That's really depressing to hear that. I gonna take some time to think what I'm gonna do next with my computer (probably following that tutorial...). Anyways, I wanna thank all of you guys who tried to help me, giving me suggestions and advice. I'm definitely gonna make more use of the forum! You guys were great and thank you for all your help, even though the problem hasn't been solved.

Yes, I have an antivirus software (MalwareBytes), and they didn't told me anything about a virus at all.

Yes, I do have them installed, but I meant that I uninstalled them when I uninstalled FSX. Sorry for the confusion.

Yes, I had SP1 and SP2, and uninstalled them both too.

I tried System Restore but I didn't get any further then the screen with ''restore points''. I can choose to at least 10-10-2012, but that's the point I decided to reinstall FSX, so that's useless. I'm very sure that the problem started 3 weeks ago (around 25-9-2012), but I can't choose that in the System Restore as you see.

I have my computer in fully Dutch. And we don't know for sure if it's update-related, but I'm gonna give it a try. I'm gonna activate the system restore, set it to 3 weeks before this topic was started. The problems then began.

I wish it was that easy and simple. I did reinstall FSX twice, and nothing changed. I think that a repair won't help either because the most extreme didn't helped at all.

I don't get a error message at all. I downloaded and installed the latest Framework, and nothing changes. Does it work to you?

I did EXACTLY what stood here, but nothing has changed. The situation is kinda hopeless right now...

Actually, that is a really good suggestion! And I can remember that I had an update the day before the problem started! I think the number of people with this problem will grow if it's a Windows Update error.

I'm currently working on your advice. My last hope :( Hopefully it'll work, or else... Yes then I would be in REAL trouble... But I'm almost done, I'll let you know when I'm done.

Not yet! We (firehawk44 and me) are working for a solution.

I tried both (making a new texture.cfg and using that registry thing), nothing changes... Thank you for helping me though. Do you have any more suggestions?

Nothing has changed. When I uninstalled FSX, I also deleted the hidden folders, although I'm not sure about registry codes. You can see what I exactly did here: http://support.precisionmanuals.com/KB/a87/how-to-uninstall-and-reinstall-fsx.aspx

No, I didn't change anything about the computer at all.

Hello Avsim! (This is the first time I post something on the forum, please correct me if I'm doing something wrong.) I've searched all around the internet, searching if someone has a similar problem. But it seems that I'm the only person in the world who has this rare problem, I think. My problem started out of nowhere, I didn't install new software, didn't change the settings of FSX and neither did I do something that FSX can't handle. I was preparing for making a new IFR flight. I noticed that the fuel parameters, in the ''Fuel and Payload section'', where changed into decimals instead of the default dots (.). Once my flight was started up, I saw the AI traffic literally sinking into the ground. It looked like this: I always press SHIFT-Z 3 times. Normally, I would see all perimeters in dots, instead of decimals, as I said. Also, the ''Fuel'' parameter is gone, which means my plane is practically unflyable, since the ''Payload'' parameter is set to full, and my fuel amount is set to 0%. When I'm going to the Map, FSX starts yelling at me that my Longitude and/or Latitude is/are wrong. Additional details of my problem are that when my plane is touching the ground, it shocks violently up and down, which has the exact same effect when you try to land a 737 with the gear up not at a runway. Also my AI traffic are all drunk pilots. When they're at cruising altitude, the ''pilot'' pulls up violently, making the plane go in a stall, plunging from 40.000 ft without reacting to it, and crashing then into the ocean or ground, with the nose fully pulled up, with 97 knots usually. My computer hasn't been affected by the problem (it keeps using dots instead of decimals), and the FSX ATC is working normally. The problem occurs immediately when start an IFR flight, using the Flight Planner, but without using the Flight Planner, the problem only occurs only when you change a plane and/or relocate your plane using the Map. When I started to get hopeless, I reinstalled FSX. But the problem is still ocurring, and nothing has changed. I reinstalled FSX correctly, using the PMDG guide to reinstall FSX. I hope someone has a solution, tips or experience with this extremely rare problem. Greets from Bas!
