A decompile will probably solve that issue.

Try this sequence (in order):

1. Uncheck the boxes under:
   Tools | Options | General | Name AutoCorrect
In Access 2007, it's:
   Office Button | Access Options | Current Database | Name AutoCorrect

2. Compact the database to get rid of this junk:
   Tools | Database Utilities | Compact/Repair
or in Access 2007:
   Office Button | Manage | Compact/Repair

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. Open Access (holding down the Shift key if you have any startup code),
and compact again.

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:
   http://allenbrowne.com/ser-38.html

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, reference ambiguities are resolved,
and the code syntax is compilable.
