When I launch Sync Beta It loads then reaches an unrecoverable error before any UI appears
"Unrecoverable error occured"
"The Port: 9666 is already in use
The application will exit now. We've been notified about the problem. Sorry for the inconvenience.
If the problem persists, Please contact Support: http://community.withsix.com"
It happens every time I try to run sync so I would say it's persistent.
I checked and no program is currently bound to port 9666
