Vista - XamlPad doesn't work with November CTP

I was able to succesfully install the WinFX November CTP on one machine.
However, on a VPC and on another machine it doesn't work. The XamlPad
won't even come up. This is the stack trace.

System.Windows.Serialization.BamlParseException was unhandled

Ok, a frien of mine has the same problem however he told me that
executing a web application works however as soon as you try to use a
library which requires full trust it breaks.

It seems that a security problem is causing this. Any fixes? Any
suggestions ?
