So I had TeamViewer working perfectly in v12, and the upgrade to v13 was fine.
Last night I installed a new video card, and TeamViewer would no longer connect through the internet, but was supposedly open to LAN connections. I've had this happen before, and after connecting locally it usually is able to connect through the internet after that.
Today I have had to reinstall TeamViewer and it is no longer working at all. The service is running, but I am no longer able to bring up the GUI.
I found the text-based setup in /opt/teamviewer/tv_bin/teamviewer-config and have been trying to use that with mixed results. Sometimes I have to run it two or three times to get it to connect to the service, and when it does it's also mixed on if it gets to the point of asking if I want to add the computer to my account. Now keep in mind if I do get logged in my computer will show up as online, though I am not able to remote in still. When I try to assign my computer to my account, I see my computer cycle between offline and online rapidly a few times before it errors out and my computer drops back offline. If I try to add it though my Windows GUI while it's listed as online, I get "SecureNetwork: Invalid Response".
Common errors I see in the logs are Errorcode=11 and Errorcode=2 complaining about an invalid private key.
I have no idea where to go from here. Reinstalling and purging the config files doesn't seem to do anything.
Edit: Here is my log when I try to add the computer to my account.
