I tried out the trial before I put in the physical version I bought awhile back. I played the trial so my buddy can get the emblem related to having a trial player in their fireteam. When I was done, I uninstalled D2 then put the disc in. Roughly 2 days after playing the game without any issues, I suddenly can't play the game 'cause I keep signing into the trial version of D2 for whatever reason. I can't go to the tower or access any locations or do any adventures that the campaign didn't allow me. I tried uninstalling and reinstalling once more, but that didn't solve the problem at all. The game is virtually unplayable now. I would greatly appreciate some advice on what to do.
