Thanks to all who responded. I apologize for cross-posting (also to the newsgroups), but I'm new and highly frustrated when it comes to VS & VFP 6.
Next issue: I'm need to regenerate Referential Integrity, and my RI builder is gone. The message (when I click on Referential Integrity in the database) is There are no registered builder of this type. Please locate the class library which contains this definition.

I've checked my BUILDER.DBF in the VFP directory, and it looked fine, complete with the RI Builder.

HELP!
