This issue was resolved in the latest version of PlayIt Live from https://www.playitsoftware.com/Products/Live
I'm having the same issue with this software. I've tried to uninstall and reinstall (twice) but it gets stuck on the Starting Sync Service and crashes. It's done this since my database server crashed.
I've sent the diagnostics but does anyone have a fix? The reinstall hasn't done a thing :(
