G2 on WINXP won't run

Hi,

I have been running G2 on my 2.4Mhz P4 with a GeForce4 MX440 64MB AGP2x without any problems.
A week ago I replaced the graphics card to a GeForce 4 MX440 128Mb AGP8x, and now G2 won't start. When I try to start the program all that happens is that the small splash screen i visible for a couple of seconds and then dissapears. No error messages nothing at all. I have tried the "CLEAN" supportcode and it didn't help. Could somebody please help me to get this working.

Anxious to fly...

Raymond
