I ran into this early today. In my case, I resubmitted the exact same question and got a good response. So maybe advice should be, "Please try resubmitting your question." Then again, I didn't look under the covers to see what was happening.

We've got some rough spots in terms of synchronization and error handling. We can give our brave alpha testers slightly better messages.
