URL relocation System.Web.Routing Implementation

We recently implemented the System.Web.Routing module for our website hosted in discountasp.net site... I have it working on our local development environment, however when I deploy to the hosted site, it does not work... (I get a "The resource cannot be found." error when I access the remapped locations, implying that its actually looking for the directory as opposed to being processed by my Custom Route Handler)...

I copied the System.Web.Routing.dll to the server bin folder.
I stopped/started app.

no luck... I would have thought just deploying the local working version should have been fine in the first place, but I guess not...

Any suggestions?
