VFP Help file gives you several pointers. Have you tried them?

From VFP Help file:

The fields in table "name" did not match the entries in the database (Error 1984)
When opening a database-owned table, Visual FoxPro tries to confirm that each field of the table has a matching field object in the database.

The database or the table has been corrupted.
Use VALIDATE DATABASE to identify the problem.

The table being opened is the wrong one.
Remove and re-add the table to the database.

>If the database is opened I get Error 1984.
