MonoDevelop Custom Syntax Highlighting

I'm trying to setup an custom syntax highlighting scheme for MonoDevelop. The problem is that i can't seem to add an new one using the add button it always gives me errors. The weird thing is that even the ones that are provided with MonoDevelop (downloaded from github) don't wo开发者_运维知识库rk via de add button. I found some examples on the net, but they also give errors.

Does anybody have any clue whats wrong, or what i'm doing wrong.

Thanks for your Time, Richard.
