Help! I am getting a random error message that mentions a .dba file when I open certain tables, even though DE 8.5 doesn't use .dba files.  If I click "Ok" on the error message many times, it eventually goes away and I'm able to access the table.  However, this makes accessing the table very frustrating and time consuming.  Any ideas on how to get it to stop?

The error message is wrong. it say DBA but the problem is a missing .TDF file.
It is something in your document that reference a column in a table that no longer exist.
