MonoDevelop Error

I am trying to use MonoDevelop 2.4 for the first time. Problem is when I open it all I see are little boxes where text should be. Any idea why this is happening. Also there is a later version of MonoDevelop (2.8) Can I or should I use that with Unity?


Bump-I open up a script with Mono and see nothing but boxes…has anyone any idea
this is happening?
