DL'ed, used the given aawdemo code for the fields, and got this: "Quota for concurrent users for this application is filled. Wait for another user to close the application."
Any suggestions/explanations?
EDIT: Waited about 10 mins, it's working now.
EDIT 2: Well, restarted the game, and it's doing it again now. I thought the blog post said it only needed to auth once on the first startup? Is there some kind of user limit on the demo?
