I have tried every patch.......4.02, 4.05b, 4.13, and 4.20, and i absolutely cannot get it to work...it always says that botpack.u is corrupt and that i need to download the patch again.....but i got the patch off of a cd after i downloaded it, and that didn't even work. I have a k6-2 450 and a banshee......this isn't a hardware problem, though. The game will run and work on the origional version on the cd, but i want to update it and i cant. Any suggestions would be appreciated.
