Hi All,I'm having a problem and am at my wit's end- I'm hoping there's a quick solution that I've somehow missed before I resort to a complete re-install of FS9... which may not even helpYesterday my system was running perfect, no problems (as it has been for a long time). Then I decided to install a bit of new scenery- the San Diego Corenado Bridge and a new Sarasota, FL. scenery pack (from a designer who's done some great stuff before, so I trust it).On starting up FS after placing the files appropropriately, the program started to build up a new scenery file (as expected), though it took a real long time so I felt something must be wrong. Then up popped the error message "Out of memory, FS will shut down. You may not have enough room on your...etc." I knew many people have reported this problem after a scenery install that somehow went wrong.So I checked all the posts on the subject and (I think) followed the directions to remove all offending new scenery files that could be causing the error. On startup FS started to rebuild its scenery file again at what seemed like the right fast pace, but then, just when it seemed like it was complete, up popped the "Out of Memory" message again!I looked at some other posts which led me to think I may have a corrupt Page File, and tried to create a new one by changing the virtual memory settings and rebooting, then switching them back, but again no luck- FS won't start. I then went back to an older restore point well before this all occured, but the problem came along to that restore point! I even ran a Chkdsk /r, and it found no problems at all.Anyone have a thought on what may be happening here, or some step I missed in fixing the scenery problem which is preventing FS startup? I'm on XP Home.Thanks for any assistance you might have for a simmer about to rip his (remaining) hair out,Joel

Hello,I had the kind of message when creating the FSNAV DataBase after adding a large mesh in my scenery directory.I did solve it with increasing the Virtual memory size also called the page file :Start/right click My computer/ properties/ Advanced/ Performance settings/ Advanced/ Virtual MemoryHope it helps

Yes, for sure check the virtual memory settings. How much disk space do you have left? If your drive with a page file runs out of space, you will get that error.

I've got tons of empty space on the drive- about 3/4 of a 120gb drive is empty..So "actually" running out of space isn't the issue...Best,Joel

Do a search on your fs9 folder for all files named scenery.dat, then sort them by date. The most recent one will point to where the sim is failing, and the offending bgl. Remove the .dat file, and rename the bgl to see if this isolates the problem. Likely the scenery you installed isn't entirely gone. This error message says out of memory, but is really caused by a bad scenery file.-John

John,Thanks for you reply, I think that is where I'm going wrong. Could you tell me how to open the .dat file (what program to use), and in what way its contents will tell me which is the problematic scenery?Thanks,Joel

You don't open the .dat file at all.... When MSFS detects new scenery, it builds index files--the scenery.dat files to which I refer. Sometimes, a problem bgl will make the process fail while it's building the scenery.dat file. The datestamp of the scenery.dat file (you have to search thge fs9 folder and all subfolders) will tell you WHICH bgl is causing the problem, because MSFS will always try to create the scenery.dat file in the folder where a new bgl is installed until it succeeds. Once that happens, it never touches it again unless another new bgl gets dropped into the same folder. The scenery.dat file simply serves as a telltale sign since there's one for every folder where scenery is installed.-John

John,Thanks for your efforts, unfortunately the problem may have been caused by some bad scenery or an installation of scenery that wen't wrong, but the fix will lie elsewhere- I did everything, including a complete emptying of the offending scenery file (identified as you suggest, and the one where I knew changes were made) and the problem persists... and occurs even if I back up to a restore point months ago, before the scenery even existed.i think I may have to resort to a re-install of FS9, I've heard of others having to do this for one reason or another but I was hoping to avoid it in my lifetime:-)So anyone with a tup on making reinstallation as easy #### possble, I'm all ears!Best,Joel

I just had the same error with apparently some faulty AFCAD2 files (*.bgl) in my /addon scenery/scenery folder. After I deleted "SIMFLYERS_AF2_KMCO.bgl" everything was fine again. Try to remember what you installed last to FS9.HTH,Boris

Are you using FSGenesis landclass? As stated in the FAQ, if it is to be installed in a separate folder that folder must not contain a texture folder or it will cause memory errors. I moved the landclass file(fsglc_us.bgl)directly into the fs2004/scenery folder as stated and no more memory problems.
