Yea just sit in their TS until you get to talk with one of them. It seems they either ran out of instance IDs and haven't gotten more or missed your server. You likely just have to check with them.
Just give it time. They have to get an instance ID for you and then they'll apply it. Mine took 30 minutes to an hour to get. Just keep checking the instance ID every few minutes to see if they've done it yet.
