Contribute 3 Uninstall Problem

I have uninstalled Contribute 3 from my laptop. However, now whenever I try to delete a file, for instance from "My Documents," immediately upon right-clicking the file, I get a "Contribute 3" screen with the message "Please wait while Windows Configures Contribute 3." I have to click "Cancel" about three times before I can take action on the file. How do I uninstall whatever is left that is causing this screen from continuing to come up?
