I was prompted to ask my partner to update her Team Viewer software when I tried to connect, and when I checked for updates, I noticed that my software was also out of date. So my partner and I both just updated our TeamViewer software. After downloading the latest version to my Mac, when I checked for updates, I got "You're up-to-date! TeamViewer 10.0.140455 is currently the newest version available." However, when I try to connect to my patner's PC, I get this message: "Your partner uses a newer version of TeamViewer. You need to update TeamViewer to establish a connection." This person is very computer illiterate (which is why I am trying to connect and help her). She's using a PC, and probably Windows 7. Not sure what to do next to fix this problem.
