Default [Q] Music Library 2.5

I have some old software Music Library 2.5 developed by William McCain quite some time ago. I have used it to control my Sony CDP-CX450 CD changer for many years.

A recent computer rebuild means I have lost the use of it. I have the entire directory containing the .jar files and database, I also have the pass code but cant get the program to run. I thought the best way would be to find the original installation files but I no longer have these.

I have tried contacting Mr McCain but his website no longer works and he has so far not answered my email.

If anyone has the installation files or can help me get the .jar file to run I would appreciate it.
