I am having similar problems, too, with posting to Blogger, although now the error message I get is a -1. I have submitted a ticket to support (Ticket #746409) a few days ago and so far no resolution has been provided. I am sure they’re working on it. I also have problems posting to the Google+ Community (Ticket #848918). Main reason I purchased the Pro version is the ability to post to Google properties. Hopefully these things get sorted out soon.
