One cause of this type of problem is trying to open a newer version database
(or table) with an older version of Access.

Another cause is corruption of the table/database.
Here is a standard sequence to try to rescue a corrupted mdb

0. Make a backup copy of the file.
00. Make a backup copy of the file.

1. Uncheck the boxes under:
Tools | Options | General | Name AutoCorrect
Explanation of why: http://allenbrowne.com/bug-03.html

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 includes the quotes:
"c:\Program Files\Microsoft office\office\msaccess.exe" /decompile
"c:\MyPath\MyDatabase.mdb"

4. Open Access, 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, and reference ambiguities are resolved.

If it is still a problem, the next step would be to get Access to rebuild the
database for you. Follow the steps for the first symptom in this article:

First, always work on a copy of the database. Working on the original may
make it impossible for a repair service to fix it.

Decompile your database:

Download a copy of JetComp.exe:

Try backing up your forms as text with the undocumented SaveAsText
LoadFromText functions:

Also have a look at the Microsoft KB article:

http://support.microsoft.com/default.aspx?scid=kb;EN-US;209137

Then have a look at Tony Toews' Access Corruption FAQ at:

http://www.granite.ab.ca/access/corruptmdbs.htm

for some suggestions. Unfortunately, some corruption cannot be fixed - you
may need to create a new database, import what can be salvaged, and recreate
the rest.

Although it's a paid service, Peter Miller does an outstanding job of saving
corrupt databases. Try this URL:

Ignore Aaron. He is the resident troll with one suggestion for every
