I have had a TeamViewer (free) account for a few years and used it successfully. I have it installed on 3 Macs. Although I haven't used it for about a year, I am now in France and tried to login to my home iMac to resolve a problem on my home network. I can't login to the management console as the system says my e-mail address is unknown! It has not changed. Moreover, although I know the IDs and passwords for my machines I note that the password displayed on the one I have with me has changed. What is going on?
