Dear cheiboy,
First, you need to have a good copy of your 'Access97' mdb.
1) Backup your Good Access97 mdb first!!
2) Run Access97, open your access97.mdb, select compact and repair.
3) While running Access97, open a code window, select compile and save all. This needs to work, or the mdb is not good.
4) While still running Access97, open a code window, select Tools>References and make a note of all references. You will need these references or their later version set in your new 2000 mdb.
5) Run Access2000, open your access97.mdb, select Tools>Database Utilities>Convert to current version.
6) The Convert will create a new '2000'.mdb based on the name and directory you told Access to create, so close the 'Access97.mdb' and open this new 'Access2000.mdb' file.
Note, you must close the 97.mdb and open the 2000.mdb at this point!
7) Finally, this is the most important step! In the new 'Access2000.mdb', open up a code window and Select Debug>Compile.
Note: The compile must work completely, if it does not, then check the 'References', that we wrote down in Step 4, to make sure the same (or later version) are selected.
Good Luck,
