Sorry , error message is in german, here is the translation:
Project ... with unknown itemtype .... could not be loaded
Bug takes place only the first time you start Mono after update.
After restarting Mono, Mono installs something and everything is o.k.
Should be fixed in more recent versions of Xamarin Studio.
