I've been using teamviewer for years, but all of a sudden, it's asking me for authentication partner's password. I set it up long ago and it just connects my tablet to my PC just by choosing the PC and clicking the remote control button. Now when I select my PC and click the remote control button, it asks me for a partners password. I haven't changed any of the setting and I don't know what password it wants. I tried all of the passwords I saved for teamviewer and none of them work.
