I have a quad core Intel system with 4GB ram and two Invidea G FORCE 8800 GT cards running Windows 7 64 bit. Recently purchased IMagisim KSJC scenery and initially when I would start FS9 I would get an error message stating that there was not enough memory and FS9 would shut down suggesting to run disk cleanup. I checked and I still have over half of the hard drive unused. I created a new Addon Scenery Folder and installed just a few sceneries. FS9 will open up but there are textures missing now from the sceneries including freeware sceneries and Fly Tampa Seattle. ARGH what is causing this. How can I fix this. I have tried re-installing the sceneries but to no avail. My Dream Team sceneries seem to be unaffected. Another thing is I cannot install sceneries from the settings panel of FS9 anymore. I have to copy and paste scenery files into FS9/addon scenery/scenery and textures into FS9/addon scenery/textures. Any assistance would be greatly appreciated.
