History Mode Does Not Advance

SOLVED

When attempting to "Finish Entering History" I get the following message

Checking Vendor....

This module cannot leave history mode because the 'Prepayments and Prepaid Orders' linked accounts is not defined.

As it stands Vendor linked accounts are:  Bank, Accounts Payable, and Freight Expense.

Prepayments and Prepaid Orders have been deleted from 'Vendor Linked' and 'Chart of Accounts' as these accounts are not needed in our particular case.

Can you suggest a solution?
