"Serviio.app" is damaged and can't be opened. You should mov

Upgraded from 1.0.1-osx to 1.1-osx and get this error when I try to run Serviio.app
I also get the same error after installing and running 1.0.1-osx now.
Any ideas or thoughts as to what is causing this and what I can do to get Serviio running again? I've tried cominations of unistalling, rebooting, installing, rebooting etc....
This error is appearing in the system.log
