I am having major problems with Medieval II total war. I have the required amount of free disk space, ram, and the latest Nvidia drivers, but it still crashes! while playing on the battle map, the terain and buildings will turn black, or transperant, and the units will stretch across the screen. I have set the graphics to low, turned off antianalizing, and Vsync, but they do nothing, i have downloaded version 1.01, 1.02, 1.03 and none of them work. i do not know what "unpacking" is and have never done it, i have manually uninstalled it a few times, but that has only exacerbated things. At the least, i need to know how to fully wipe this game from my computer and perhaps totaly start from scratch with all the drivers and stuff, i realy need some help and it will be extremely appreciated!!!
