I have come across this problem as well, but my situation is a bit different (odd.) I originally setup the x2go client on my work laptop and it connects just fine. I wanted to add it to my personal laptop (both run Win7, but home is regular and work is Professional) and that is when I run into this issue. I've tried uninstalling and removing the registry entries for the application, no-go. Is there a workaround for my situation? Thank you, David Christensen
