We had an issue with the release we put out on May 12th. Our issue results in all sending activity occurring through your primary account (not any additional accounts).

We put out a release last night and another one today that addresses the issue.

Also, if the number of messages or videos you can send is significantly reduced you should stop trying to send for 24 hours (including directly from www.youtube.com). Due to the fact our software was sending messages only from the primary account, YouTube may be restricting the sending from that account.

Sorry for the inconvenience.
