I have faced this problem even though I hardly use TeamViewer for 10 minutes a month for helping out friends and family.
Looks like the complicated way to get around the problem is to clean up TeamViewer data from your computer:
Delete the TeamViewer folder in %appdata% folder.
Remove the registry key: hkcu/software/teamviewer and hklm/software/teamviewer
And then you would have to change the MAC address of your networking hardware. There are plenty of free apps available online that can help.
The problem with changing your MAC address is that it would break some other apps on your machine like the Google Music Manager.
