Hi Nats,
Open Access. Then click File/ Open.
Locate your MDB file and don't double-click it. Check the "OPEN" button and click the little triangel at the right part of the button and choose OPEN EXCLUSIVE.
When opened, go to TOOLS/SECURITY/SET PASSWORD.
If you have already set a password you will see UnSet PASSWROD. You need the existing Password to remove it.
After removing, set it (the new password) again.
Try this, it will work.
Cheers
