I accidentally set up a new user when I installed after formatting my drive. Now, I don't see a spot where I can "log out" and use my previous information to log in with all of my old cards. I've even tried to uninstall with Windows' and with Total Uninstaller, then re-install. I've checked the registry to ensure that no traces are left behind, but somehow, it automatically goes to my new account.

Can anyone help me?

Thanks in advance...
