CMR DiRT crash

[n00b_bi22o]

i was wondering if anyone is having the same problem as me:
when i start up the game, windows displays an error message, that dirt.exe encountered an unknown problem...etc
i'm using winxp sp2 with 162.18 WHQL display drivers, up to date dx9c, the game patched up to 1.1 with RELOADED crack... (i've tried the original exe, same problem)
specs:
AMD Athlon XP Barton 3200+
2,5 Gb 400Mhz DDR RAM KingMax
inno3D nVIDIA GeForce 7600GT
(i dunno, but maybe my processor is unsopported, but im not sure, because i've read other forums and others had this error with athlon x2 processor...)
