Every time I join a game I get this I never can play, I have 1 character I made a new character to see if that would effect it it did. I can join with a character I just made but not the level 70 that I have… Is there any fixes for this or do I have to make a whole new character… If so I wasted my time 100%'ing play through 1 & 2… Any help would be appreciated.
