Dimension is not opening properly.

Hello all, when I went to open dimension for the second time today all that came up was a blank screen only showing the x-out, minimize, and elarge buttons at the top right (attached below). I have quit all other adobe apps, tried x-ing out but it does not respond, and retstarted my MacBook Air. I have also tried installing a different version of dimension as well as uninstalling this version although I can not do either because I must close dimension before I do either. Any advice helps!
