Cannot install 1.1 patch on windows 8.1 (Just want multiplayer to work... :( )

[bobafett99]

So whenever I try to run the 1.1 update, it says it can't find forces of corruption or empire at war, and to reinstall and try again. I did this.... But it still won't run. I have a feeling that's why my multiplayer lobby keeps freezing, and I really want to play TR multiplayer. This is a legitimate , no-crack, gold pack install.
