The database has begun to corrupt.
Suggested steps to recover:
1. Uncheck the boxes under:
Tools | Options | General | Name AutoCorrect

2. Compact the database to get rid of this junk:
Tools | Database Utilities | Compact
3. Close Access. Make a backup copy of the file. Decompile the database by
entering something like this at the command prompt while Access is not
running. It is all one line, and include the quotes:
"c:\Program Files\Microsoft office\office\msaccess.exe" /decompile
"c:\MyPath\MyDatabase.mdb"
4. Create a new (blank) database. Turn off the Name AutoCorrect boxes for
this new database also.
5. Import all objects from the old database:
File | Get External | Import
5. Open a code window.
Choose References from the Tools menu.
Uncheck any references you do not need.
For a list of the ones you typically need in your version of Access, see:

6. Still in the code window, choose Compile from the Debug menu.
Fix any errors, and repeat until it compiles okay.
At this point, you should have a database where the name-autocorrect errors
are gone, the indexes are repaired, inconsistencies between the text- and
compiled-versions of the code are fixed, the objects have been recreated,
and reference ambiguities are resolved.
If these reports are still bad after this, post back form further
instructions on using SaveAsText and LoadFromText on these reports.
