So I bought the game over at my buddy's house on my Uplay account, installed it there, and got to play with it for a bit before having to head home. I logged on to my Uplay account at home and installed the game, but when I tried to Install it, it said that it wasn't able to. Verified the files; all there. Do I have to uninstall FC3 at my friend's house for it to work at mine?
