Basically, when i run the install wizard for the patch it gets to about 13% and sais it cant continue cos the file required is not the same version as it used to be, or something like that... any help?
If you aren't too far along in the game, you might try uninstalling both the game AND the patch, then reinstalling (game first). Personally, I've found that the patch didn't fix a blasted thing, and I'm so far along in the game that I'm going to wait until I finish, then uninstall and try reinstaling.
