Hi, Mike,
PwC gave some good advice.
Within the Maintain specifications window, you'll want to ensure that the path specified to the Receipts spec is the correct one.
You can also drill down to where PO is installed and determine if the correct report does exist in the Softrak\POWIN\Reports folder. If it does, select it. However, you'll want to be sure to click the 'Save Specification Path' button before leaving the Maintain specifications window to ensure both the correct path and filename are saved.
