I have a new local user and a new PSN account. Prior to signing in to PSN attempting to launch the game would result in a "sign in to PSN" message, hence why I created an account and signed in. If I remove the PSN account I would presumably end up stuck at that error message.
Sorry for the necro.
The account I have was not the original purchase account, can I still activate via PSN or should I use the evilnat option to create an act.dat?
