ChemDraw ChemFinder: I receive the following message when I attempt to import an SDF into ChemFinder - Could not lock table "MolTable"; currently in use by user on machine

I receive the following message when I attempt to import an SDF into ChemFinder:

Could not lock table "MolTable"; currently in use by user on machine .

This happens when trying to create a new column in a table while that table is open by another user. If anyone has a recordset open on that table, you are prevented from modifying its structure. Pre-create the columns needed by the sdfile before importing.
