Hi,

There seems to be some change in the permissions, and that the user to
access the assembly is now denied access. You would most likely get the
same error message if you run this as a stand-alone application with the
same user as is used by your webapplication.

Verify that you are still using the same user account for your
webapplication, as you used before this started to happen. If you do, it
does not seem to be a problem with IIS, but more of a programming problem
(related to security). I would recommend you to post to a programming
newsgroup, or possibly a MSProject newsgroup for faster and better help.

Good Luck!
