The WebAssistant not working any longer

The WebAssistant was working properly for me (2 days
ago), now I
cannot get it to start, even for new projects.

 - I had a small DTW app, WebAssistant working
properly.
 - I added an EOModel from another application that I
was integrating with.  The added Model had some custom
classes defined, which my app did not have.  I
attempted to access the WebAssistant and got the
following error.
- I now get this error for all apps, including new
ones that have no custom classes.
- Is there a registry key, config/property file that
may have gotten corrupt that controls how classes are
loaded from a model?

I don't really care about the app that I was building
as much as the fact that the WebAssistant is hosed for
all apps on my system.

Note: All of my tables are defined and so are all
classes.

Any help would be GREATLY appreciated!!!
