Hi, welcome to TSF
Patches usually rewrite the main exe file and other system files related to the game, and sometimes edit the registry, so it's much easier to just backup your saves and reinstall the game rather than trying to fix it manually.
In most cases, it's not possible to uninstall the patch to roll back to the original version as there is no backup of the patched files.
Have you checked the FIFA08 forums to see if this is a common problem?
Did you follow the instructions and install the patches in the right order?
Did you download them from a reputable site?
Did you test the game after each patch so you could pinpoint which one caused the problem?
