When starting FS9,an error box appears saying,youre computer has run out of available memory,flight simulator will now exit.I know thats not true cause i've a gig in my pc.I just got this message today when i was placing static scenery objects in my area on fs9.can anyone please,please tell me how to fix this problem.

there's your problem. Undo whatever objects you were placing, something is amiss. FS9 can be a bit touchy with incorret objects, duplicate AFCADs etc...

I had this problem and I solved it by going to control panel-system-advanced and clicking the performance and then advanced tab. There are some settings you can change under virtual memory. Again this helped me but may not help you. Maybe someone that knows a little more can help. I can tell you though with me it had nothing to do with any scenery cause I cleared it out ans still had the problem.Good Luck

It is very likely your problem was caused by an incorrectly placed landclass file in an addon scenery. Do a search on here for "landclass" files. Peter
