Your database is corrupt.
The first thing to do is to make a backup of this database file and put it
in a safe place.
Next open up just Access, then do a compact and repair. After opening up
Access go to the Office button, Manage, Compact and Repair database, then
fine the problem database.
If that doesn't work, hopefully you have a recent backup.
Tony Toews has an excellent web page on database corruption.
