When I boot up I get a small window that states, "Error starting Program". "A required DLL file QDCSPI.DLL was not found".

How do I get/find it so it is usable? I am using Win 98.

Are you running Norton? If you are Norton suggests unnstalling & reinstalling the program.
You can download the dll here http://www.dll-files.com/dllindex/pop.php?qdcspi
Download the file, unzip if its zipped and place it in c/windows/system.
