Thought I would try this group to find an answer:

I created templates in Dreamweaver CS4.  I upgraded my machine to 
Contribute CS4 (Adobe content management system).  My users, who are 
still using Contribute CS3, cannot access the newly created templates.  
All templates prior have been created in Dreamweaver CS4.  My users can 
still create pages based on prior templates and publish to the server.  
Anyone come across this?

Thanks.
