Hi Elyse.

>I chose a file that was a free table in the old data but had since been added to the DBC. This file DID need a structure change as well.

OK, I tested that scenario and found that indeed it didn't handle that case. I've now taken care of that and emailed you the updated SDT.VCX. Please rebuilt SDT.APP and let me know if this resolves the problem.

BTW, you'll use the Update() method rather than the Update button in the Database Explorer to update files at your client site, right?
