Wow I thought I was the only one, I just started getting this error. Bought stuff on the auction house and went to play, but it wouldn't go in game. I closed the game and now I can't log in :|.
Bump. add me to the list of unhappy players! Time for CoD and WoW. Blizz, please do something!! (I'm sure you are, sorry to chastize.)
I just started having the same issue about a half hour ago. It happened right after I had purchased in the Auction House. Hadn't had this problem before. I see they had a similar problem back on 5/30 2013. Hopefully they will fix it soon. At least they are enough of us having the problem that they can't ignore it.
I just got the game a week ago, figured all the kinks would be worked out by now..... very dissapointing
Well, tried again and it said the server is down for maintenance. At least it means they're working on it... I hope.
Says to check server status page for details. There are no details on the server status page.
