[Zope] Data.fs gone crazy

[Tom Cameron]

When I am editing an ZSQL Method and I click on the 'Advanced' tab I get
this response:

Error Type: ImportError
Error Value: No module named POPMailBase

Traceback (innermost last):

POPMailBase is a completely different Product that I removed a few days ago.
How could the two be related and how do I fix this mess?

My Database connection keeps dying now and I cant seem to get it to work
anymore.

This is a Windows 2000 machine zope 2.3.2
