This method for repair mdb file may help if your database is already corrupt or in case neither article nor mentioned links can't help you

Here you may find solutions that are probably more effective than others - http://www.databasejournal.com/features/msaccess/article.php/1494111/How-to-Recover-a-Table-Deleted-from-an-Access-Database.htm

It is the resource of this article: http://allenbrowne.com/ser-47.html

And two alternatives https://recoverytoolbox.com/repair_access.html or http://www.mdb.repair/

Before doing anything else, make a copy of the corrupted mdb file while Access is NOT running, and without overwriting any earlier backups. This lets you try different approaches and sequences if necessary.
Next, try the built-in repair utility. This very simple solution may work with corrupted indexes, and might even get rid of a corrupted object: click Compact and Repair Database on the Database Tools ribbon.
