I bought the GotY version from Wal-Mart a few years back, when I first started getting into PC gaming. Popped it in, discovered my Windows wasn't compatible and haven't touched PC gaming since. Then I got Fallout: NV later last year, and was complaining about how F3 was apparently a waste of money when I was recommended here.
I re-installed the disc-version of Fallout 3: GotY, updated it, and went to install TTW. It's telling me my .esm and .bsa files of Fallout 3 and all of it's DLCs aren't supported. So, is that it? Am I outta luck again?
