Exit the application, correct the invalid entry using Microsoft Windows Notepad or another text editor, then try the operation again.
The ParadoxNetPath entry in the [Paradox ISAM] section in the .INI file points to a network drive, and that network drive isn't connected. Check to make sure the network drive is available, and then try the operation again.
