*Resolved* Error when running ASP.Net app with Crystal Viewer

I have an ASP.Net, VB.Net app that has a form with a Crystal Reports Web Viewer on the page. When I do a redirect to this page, I get the following error

This error happens on any page that has a viewer on it. I have checked my references and they seem to be in order. The project will build without any errors. does anyone have any ideas?

Resolved! I unloaded Crystal from the .Net environment and re-installed and that fixed the problem.
