i'm hoping this is the right place to post this, if it's not then i apologise...
I have 3.0 (with the 3.1 patch), (installed in a different directory to FS2) and I also have FS_open_3.6.5 (i think) which works fine.
Basically it crashes upon first trying to play a mission. Goes through the briefing fine, but when i click on commit it CTDs in OpenGL mode (but not in direct3d). After re-loading the mod and going through again it works however.
System specs:
Windows XP (Professional) SP2
AMD Athlon XP2600+
Leadtek 6600GT
1024MB RAM
as it does work in direct3d it's not that much of an issue, but thought it should be noted if it hadn't been already
an excellent mod!
