Update!: I (hopefully) updated my ATI driver correctly.(When I tried to uninstall the old one, it said it didn't uninstall correctly but whatever) Anyway, just wanted to tell you so you don't have to tell me how to do it.
Actually, if it matters, in my first link where it shows you the how-to vids, in the last one that teaches you how to install the new driver, everything that happenes after about 3:05(accepting terms and agreements) and after that doesn't happen for me. I don't know if that's good or not.
