Error on startup: Service 'Sdl.Desktop.Platform.CommandBars.IActionService' could not be started.

When starting Studio 2014 I get the above message. The complete message reads as follows:

<SDLErrorDetails time="04.12.2014 18:16:00">

I'm fairly new to Trados and completely clueless. Their support is a joke, too, I look around for answers and all I get is a hefty offer to pay $200+ to log a support ticket. All input on this would be appreciated.
