Where's online help?

I'm completely locked out of TeamViewer. I send a request to extend my trial (even though I'm not on a trial) expecting it to fix the problem but nothing happened. I'm looking for how to chat to a TeamViewer team member to get this resolved quickly.

"Correct the highlighted errors and try again." What errors? Nothing's highlighted! Can't even post a message asking for help! Do you see why I'm VeryVeryAnnoyed?
