I seem to have lost my PM inbox. Did anyone else lose theirs?
What do you mean exactly by "lost?" Can you not access it anymore? Are all your messages gone? Can you send new ones?
There's a button you can hit in the messenger that says "Disable Messenger." If this got hit somehow, it could be the source of the problem.
I don't think anyone else has had trouble with PMs, but someone please correct me if I'm wrong.
