Can't click on anything in Cubase Elements 6

I recently purchased and installed Cubase Elements 6 on my Mac, and everything seemed to go smoothly so I started up the program. Major problem right from the start - no buttons or options will respond to my mouse clicks. Right when the project assistant window opens, I can’t select any of the top options (Recent, Recording, Scoring, etc.) or the presets within each option. I can only navigate with my arrow direction keys.

Once I do start a new project, just about everything is unresponsive to my clicks. This includes the transport control, mixer, and option windows do open but I can’t click anything in the window, such as Device Setup (can’t select my audio interface) and VST Instruments (can’t click a blank box to select an instrument).

Needless to say, this has rendered Cubase unusable. Has this happened to anybody else? I’m using OS X Mountain Lion 10.8.2 on a 2013 MBP 15" Retina (2.6 GHz, 16GB memory). Cubase 6.0.7. Thanks for any advice you can provide.
