Locked out after update

[DrewT]

I ran the update compatibility check under tools and it told me to update the Myserver plugin. I did that, and after the update completed my key stopped working. I clicked at the top right and it popped up a window saying my license may have been blacklisted? Now nothing will work. What did I do wrong? How do I repair?
