Failed to load expression host assembly. Details: Security error. (rsProcessingError)

    Yello, I'm getting an error when generating a report that doesn't appear to be listed in the documentation, so I wondered if someone here could give me a few pointers. 
     
    I'm having a tinker with using external assemblies within the report, and running a preview of the report within Visual Studio works a treat, i.e. running it against localhost.  However if I attempt to look at the report via the browser, or deploy to another server and browse from there, I always get this message:

    I'm certain that the assemblies are available to report services, they're sitting in the gac with the .net trust set to full, and any dependencies are also in place.  So I'm a tad confused, anyone who can help will receive much virtual loving.
     
    Thanks.
    Martin.

    Did you ever figure this one out?  I am having the same problem.  After rebuilding with the most recent version of our program (which works for my coworkers) when I try to view any of the reports I get...

    I have restarted Reporting Serves and replaced the new .dll in the Report Designer folder.  I can't imagine what to do next?

    Thanks,
