GB error on authenication/login

[290505735]

I get this error message on my GB when

Init: System.NullReferenceException: Object reference not set to an instance of an object.
at ..()
at ..(Int32 processid)
Cannot start - reinstall Gatherbuddy.

I've tried reinstalling, installing the .NET and I'm still getting this error.
