You could try deleting the DCX file which is the index file for the DBC. Close the database first, then erase the DCX file. Next open the database exclusively. If that works, issue a VALIDATE DATABASE RECOVER command.

For tables, you can erase the CDX then open the table exclusively and re-create your indexes. It will be better to create the indexes as opposed to a reindex.
