Hey there, I've got a new computer and I'm reinstalling FIFA 13 on it. I have the game disc, but for some reason my Win8 won't read it, so I had to download it off Origin (since I already had it registered when I installed the game in my previous Win7 PC). Here's the thing: I want to mod the game, but I don't wanna have to reinstall the game if something goes wrong and I want to return it to default settings, 'cause it'd mean I'd have to download it all over again and my Internet is insufferably slow. So my question is: which files should I back up if I'm unsatisfied with a patch and want to return FIFA 13 to its original state without uninstalling it from my PC? Thanks in advance.
