A reserved error indicates something happened that the MS Access developers
did not anticipate, such as a corruption in the index of the database, in a
memo field of a table, or even cross-linked sectors on your hard disk.
Make a copy of the original database (without overwriting any other
backups), and try repairing it:
Tools | Database Utilities | Compact/repair
This error will occur if you change the design of a table, but don't follow
through with a compact. If your database is split, it is a good idea to
compact the backend after a design change, and also refresh the links in the
frontend and compact it.
