Big problem with game. Corrupted

[Boores]

Good evening. I have installed the spanish version of this game published by friendware. I have installed the uber patch, but the game when i try play is corrupted, the graphics are corrupted. I have a AMD dual core 3800+ and four modules of kingstom hypermemory 1024 megas each one, and a ATI 4670graphic card by Asus. The S.O is windows XP with service pack 3 installed.

I have just installed the latest drivers of Ati catalist 9.4


Thanks for the help that you could give me; I wanna play with my game, before the ATI i had a Geforce 8600gt and the game ran,now with the ATI crash.


I selected on control panel "use aplication settings" for Antialising and turn off the adaptive antialising, and when i play a scenary where is raining the game is less corrupted and when play a sunny scenary the game is a dance of big shadders on the screen, it´s impossible play with that problem.

I try with all variations on video menu of the game, only one CPU or without shaders, or less detail, but nothing. Please i need a solution
