Dude Client Suddenly won't launch

This morning I opened the Dude and I get a message asking me to select language. If I click OK the same msg just keeps popping back up. Tried uninstalling and reinstalling but same problem. The windows server launches fine from the server and other clients are ok, just not this one. I’m using version 3.6 with windows 10.

Any ideas?

In case anyone else comes upon this, uninstall and reinstall does not work. Uninstall, search for all files named Dude on main drive, delete them all, restart computer, then reinstall dude. Works fine.
