Ok, i have the same problem that the game crashes to desktop. I have been trying everything that have been listed in this thread and its still not work!! I also have AMD athlonXP 64 and windows XP sp2, maybe it is something with 64CPU but i have not read anything about it.. I had a software once that didnt work with my AMD64, but it was solved by entering some string in the programcode =) I hope someone soon will come with a solution, a patch or something..
Could you, who were able to start the game tell us wich cpu you´re using, please?
I have a Sapphire radeon 9250 GF Card with the lastest Omega driver, not the best card in the world but it should work..
