I can complete the first mission in the campain but when I try to load the second one the game quits to the desktop. Please Help Me.

I'm having the same problem. When I try to run the A-10 Escort mission the program quits. Is there a fix for this? I already applied the 1.02 patch.
My computer:

P4: 3.4Ghz HT
2GB memory
ATI Mobility Radeon X600 w/256MB RAM
Conexant Audio

Thanks

I had the same problems. Till I have downloaded Flaming Cliffs add on, everything is OK.
