I had the same problem with over 40 posts prematurely published. I deleted the updated version and manually installed the one ending in .4444. The plug-in was working fine before the updated .6666 verion. Is there any reason we even need to update it? I had to manually change the status of my prematurely published posts to draft, will have to manually reschedule them. If this happens when I am overseas it would be a disaster as I only want one post per day being published.
