April 2000 means Zope 2.1.6. I use such a "Data.fs" without
problems with Zope 2.3.3.

There is a conversion utility in "utilities" to convert
really old "Data.fs" files into a new format.

This is probably a different problem:

Your "Data.fs" appears to use Product that is not installed
in your new Zope installation. This gives you broken objects
(see above in the tracebach). As it does not support
subscription, you get the attribute error.

Try to visit the "Products" page:

    http://localhost:8080/Control_Panel/Products/manage_main

If you are lucky, you will see broken products.
Install them and check again.
