Maybe try clearing preferences during start up.
On Windows hold shift/ctrl/alt while the application is starting up.
On Mac hold shift/cmd/option while the application is starting up.
Good luck. Hope that it helps.
Did you shut down your machine after doing this, or at least do a restart?
This isn't an app for your phone, you know.....
