What all do you have done ?
Its odd that their code would just break.. unless they are not coding correctly and It never worked right..
I agree with Denis, anyone who uses MonoX should join these forums because these guys are great help.. they helped me understand MonoX very well.
I am not a asp.net pro either, But I am a professional .net application coder but don't do much asp.net so I had a little bit of a learning curve with the asp.net controls as well as the MonoX API and framework.
But with the help of the MonoX guys I have been able to customize a good bit of the system as well as wrote my own web controls.
