Oh and, I didn't download the game from the internet if that's what you mean. It's brand new from Amazon and it was working fine before I upgraded. (The long period of me constantly asking for help on Ides) xD
I believe it may have been the installer, as when it installed my disc drive was being annoying and decided to "not work" at the very end of the installation, where it said "Removing Backup Files". The install bar was at the very end though, so I don't get it.
