Here's the "best practices method" step by step:
Find an undamaged copy of this file. (Open it and delete some records to see if it crashes.)
Save a clone of this file.
Use Import Records to import all the records from all the tables in your recovered file into this clone.
Test the clone and see if it works.
If not, try finding all records in your recovered file and Omit the problem record. Then import these records into a clone file. The damaged record will not be imported and that may fix the problem.
