A: Go to your C:WINDOWS folder and search for the LISST.INI file. Open it up in Notepad or a similar text editor. Make sure that the section containing your instrument calibration constants are located in the file. It not, copy them from the LISST.INI file that was included on the ship disk for your instrument. Then re-save the edited LISST.INI file in C:WINDOWS.

A typical LISST.INI file for LISST-100X looks something like this; it is the bold section you need to copy to the INI file in C:WINDOWS:
