Cannot open dBase IV file

[WC Banta]

I open a dBase IV file DEMS.DBF and am taken immediately to a "Select Index
Files" window. I select the name of the file (DEMS.NDX) and am told in a new
window "Microsoft Office Access finished adding the index C:\DBASE\DEMS.NDX.
Add another index from the Select Index Files dialogue box, or click Close"
When I click Close I get the message: Select Unique Record Identifier" with
the name already placed: "NoName". There is no way to alter this name. I
click OK (the alernative is Cancel) and try to open the DEMS file in Tables
view, I get the message: "Index not Found (OK)", followed by the message
"Microsoft Officee Access can't open the Table in Datasheet view."

And there I am. I cannot locate any way to open the file.
