Kicked off Connection with use rights warning

With both systems on version 12, I was logged in to my wifes computer for the 2nd time today and was kicked off for 2 or 3 minutes with some warning about use rights. This has never happened before, with our free versions of Teamviewer. Has this happened to anyone else? What might have I caused the system to think I was trying to use the free version professionally? 

Thank you.
