Unable to deploy MonoTouch Demo

Hi, last week I succesfully implemented the MfA variant from OxyPlot in my Android application using Xamarin.
This week I started working on the iOS version, but I'm not able to deploy the MonoTouch Demo to my iOS-simulator on my Mac.
I've tried to implement it into my iOS app but the app won't run after I've implemented it either.

This is the error I'm getting:

Log generated on 29-10-2013 13:33:37

Operation failed (Build Server)
Operation status: Operation failed
HTTP status: 200 (No error)
OK
Build server returned an error.
Failed to debug MonoTouchDemo

Does/Did anyone have the same problem, or does anyone have a solution to this?

This seems to be a Xamarin/Visual Studio related issue.
