here's what happened:
i got a copy of Call of Duty 4: modern warfare. my computer meets the minimum system requirements for t, but when i'd play it, after about 5 minutes playing, all the textures would distort, text would become blocks, and the game would freeze, forcing me to use ctrl+alt+delete to end the process. (and yes, i DO have the latest everion of 9.0c, i installed it when it gave me the option to right after the game was done) it did this twice more, and then i thought, maybe i was just running it with the graphics settings too high. so, i clicked optimal settings, and got to play it for about 10, 20 minutes, and then i got an activision box error (i don't know what else to call them, i've only seen it from activision games) i ignored it, because it's happened with other games and i've been able to restart them fine. but now, when i try to open CoD, i get the error message you see in the image. i've tried re-installing directX, i've got the latest drivers for my everything, i i even tried updating call of duty to 1.7. and, it's not game specific, i can't play any 3D games now, despite dx diag saying i have direct draw, direct3d, and agp texture acceleration all avaliable and enabled.
