How do I disable Contribute CS5's office integration?

Hello,

When I installed the CS5 collection, Contribute installed itself into my Word and Excel toolbars. It does not seem to have adversely effected Excel, but I suspect that Contribute is the culprit causing havoc with my Word 2003 Normal.dot template's operation.  I would like to disable it from starting when I start Word (remove the integration with Word) to test my theory, but I don't know how.  Can anyone help me with this?  I use a PC with Windows 7.

Thanks!
