I'm unable to access the Titans version of the game, the option to change it doesn't even appear anymore in the settings menu. However in steam it states I own the game, I never bought the original PA just Titans, I have attempted to uninstall and reinstall, verified cache, all of that. I started having this problem when I installed the non-steam uber launcher after linking my steam account with my uber account, which I then promptly deleted and resumed using the steam version hoping it would solve the problem. Help? I've included my dxdiag
Sounds like something went wrong with your account data. Unfortunately, the only way to get that fixed is to contact Uber Support, which means it could take a while as they are currently quite overwhelmed. Annoying... In any case, Uber Support can be contacted through http://support.uberent.com/ or mailing support@uberent.com
