I went ahead and did that, but got the same error message. So, I deleted the account in BES, re-created it on the BES server, and was able to successfully register - things are syncing up now. Thank you for "looking over my shoulder"...

PS - I know it is not recommended to run this in production, but can I then push and ask about the next beta release and how it is shaping up for GA?
