Query fails after changing column name using Mascon

When I change the name of a field the mysql query fails (using the new field name). It works if I change to an existing field. If I change that field name query doesn't work (having amended the query). Sounds like my table is not being updated to new field name, so query doesn't find the new field. Has anyone come across this problem using Mascon (scibit.com) to update the table, field?
