I had to reinstall RU Host on computer after a restore. It generated a new Internet ID, which I have entered into the properties of my 2 Viewer computers. Password is the same as previously. Viewers show Host connection "online," but are unable to connect. I have restarted Host and Viewers. Using Windows 7 on one Viewer, Windows 8 on other Viewer and Host. Was connecting perfectly fine until I had to restore the Host computer, which resulted in my having to reinstall RU. (It was as though RU had never been installed on that computer.) Thanks for any insight y'all might have!
