Hello. I have a problem right now where I recently bought BTTF: The Game but on another account (not this one) and I downloaded it as usual but for some reason, BTTF is logged in as this account instead of my new account. The only solution I heard is to delete the login registry key by pressing the Space bar before I loaded it and change the login key to my new account there. It didn't work but I'm guessing that's because I am using a Mac and that solution may only work on the PC version. My big question is, how do you delete the login key or login prefs for BTTF on the Mac?
