Hello - I have learned I now have a similar issue. I have been using my free personal account without issues for years. My girlfriend then started working remotely for her employer and they set her up with a TeamViewer account using their commercial license. TeamViewer was already installed on my home PC for my free personal use, and so my girlfriend logged into her provided commercial account through the same TeamViewer installation on the home PC. We were not aware of these limitations, and now it appears I cannot use my free personal account as it now thinks this is an expired commercial license. From researching/troubleshooting, it looks like the only way to get around this would be to change my system MAC address, which indicates the device MAC address is likely used to associate specific devices/accounts to either a free or commercial license. Because my home PC MAC address has now been associated with a commercial account provided by my girlfirend's employer, my personal account is now also flagged as a commercial account. I would like to ask if TeamViewer support could assist with fixing this on my personal account, so that I can cleanly re-install the TeamViewer software and continue using my free personal account as I had for years. Then, now that we know of this compatiblitiy conflict, we will be sure to not use a commercial account on the home PC moving forward.
