Make sure the ManagedFusion.Rewriter.dll is in the bin directory under your project/web folder. You should not need the pbd file. Also verify the ManagedFusion.Rewriter file is in your web directory (same directory as the web.config).
Below are the contents of a test web.config file and ManagedFusion.Rewriter file we have running in a test environment. This is an IIS7.5 application with an application pool running the 2.0.50727 .Net Framework Verify you are running your application on port 8080 or update the web.config and url rewriter to have the correct port.
