Can you open up a support request for that, along with whatever information you can gather on the problem? (ie: are there any error messages in the logs, if so what's the text, are you able to post to your account through the web client, etc)

We didn't make any changes to the protocol in this code push that might have prompted that, to the best of my knowledge, but the more information you can provide, the better chance of figuring out what's up!
