Hi all,Anyone else have this issue?Since I've installed SP1C FSX has become unstable, it will just freeze in CRZ and I'll need to CTL ALT DEL to close the sim. I did a clean install of the NGX with SP1B and so far I dont have a freeze. However I have not tried SP1C without FS2Crew yet to check if the freeze is caused from this new addon. What I do know is I dont need to be doing anything with the aircraft to cause the freeze like entering stuff into the FMC, it will just freeze even when I'm away from the computer.thanksIM2

It happens every now and then with me also. I could never find how to fix it. It will not happen to much with me but when it happens it is very upsetting.

I have it continuously. About once very one or two minutes FSX hangs for 10 to 15 seconds. It comes back, but these hangs are very frustrating. It has only started happening after the install of 1C. The first flight in the 800 after the 1c install started this. I have installed nothing new as far as addons and it worked fine under 1B. Does anyone have any ideas?

Add me to this problem too. Never had any problems prior to SP1C and I have been flying it since last August. Like states above FSX just locks in mid flight anywhere from 20 minutes to a couple hours into a flight usually with nothing else going on. Very very frustrating.

I'm suffering this hangs too. It was flying very well prior to spc1, and i'm having problems in some flights.The simulator hangs just passing over some waypoint in the fmc, i think.First was in a 1.20 hour flight, after 2.30 hour flight and today in a 30 minutes flight!

Depending on how fast or slow your computer is will determine for how many seconds the freeze is. Most likely reason your having this freeze is because of FSUIPC Autosave. With the 747-400 and MD-11 the saves are not even noticable but with the NGX it takes awhile. Example on my system I have FSUIPC set to save twice an hour. When it starts saving it takes about 3-4 seconds to resume again. The reason it takes so long vs other PMDG aircraft is because the NGX is much more complex and there is a lot more data for FSUIPC to save.

While flying from PHOG to KLAX about half way through the 5 hour flight computer just froze up and not even ctrl alt del would work. Only thing I could do was a hard reboot. Gave up on that flight and waited until the next day. Tried the same flight again and this time about 1.5 hours into the flight it froze up again. Gave up on the flight and on the third day I decided to use the MD-11. Made it to KLAX without any freezes.The difference in my case is I was not entering any info into the FMC, was just at cruizing along and it froze. I am not using FS2Crew. I am flying in 2d Panel Mode, using GEX, UTX, AS2012 and FS Global 2010. System specs: Windows Vista 64-Bit, 3.0 ghz, 8 gig ram, Quad Core, 8800GTX Video Card with 768 meg vram.Prior to SP1C I was able to fly the NGX on long range 7 hour flights without any problems whatsoever. Only after SP1c did the system freeze start. After the 2 freezes with the NGX I did make a change before using the MD-11 on the PHOG to KLAX flight. I upgraded FSUIPC from 4.7 to 4.8 which just came out this month. I am going to try another test flight from PHOG to KLAX in the NGX later today. If it does not freeze then I will know that upgrading FSUIPC helped fix the issue. However I am not very optimistic that this will fix it. I am just guessing here but is it possible the move to Visual C++ 2010 with the NGX caused a problem somewhere and that there is some code that needs optimized or cleaned up?

That is the way this problem has been. It just freezes for no reason. Like you said you are just flying along and it freezes. No problems prior to SP1C. I have added no other software or updated anything else except SP1C since this issue began.

If they get enough support tickets and information and can track down what is causing it they will probably release a hotfix to resolve the issue. In the meantime you could always upgrade to FSUIPC 4.8 like I did and see if that solves the problem. Will let you know the results of my NGX test flight from PHOG to KLAX after I do it later today.

I agree people need to report it. I put a ticket in last night and PMDG support told me I was the only one to report this problem! Instructed me uninstall everything and reinstall.

Same here. Did a flight in the 800, KMIA_KDCA.. froze 30 minutes during cruise on firday. Yesterday KMDW KBUF, froze during decent. I had this problem before SPb was released. SPb fixed it, now upgrading to SPc the problems have started againSean

hmm i might be on a +1 to this. Did a flight and it freezed for 1 second just before final. Any body who knows the other issue where the NGX would freeze just 100-500 feet before touchdown ? it ruins the feel of motion .Michael

Same thing here, freezing every flight even with no add-ons enabeled.

Am I the only one who has not installed SP1c? As of now I refuse to install it. Everything is perfect - I'll live with the imprefections with sp1b. I don't want to mess with success.

Same here freeze all the time just befor touch down !!

Ryan Maziarz replied to my ticket and feels as there is no error message it could be an FSX address space exhaustion problem. I moved of few of my graphic sliders to the left a little (they were mostly maxed out) and had a good 3 hour flight tonight without a lockup!
