I try to load an Endor mission, the screen goes black, then returns to the desktop. At first I thought it was happening just on the singleplayer conquest part; now it's specific to any Endor game. So far I have ruled out:

1. Regional Settings
2. T&L renderings
3. SP2 and DirX 9.0c drivers

Everythings else works fine now, three installs and a zillion minor changes later...

Is this happening to anyone else?
