I realized after a recent hard drive re-install that I was using an unregistered copy of dBpoweamp and upgraded to a registered copy and now have version 15.1 installed on my desktop. Since the upgrade, however, the converter does not work at all. I can select the files to be converted and they appear in the file list. When I click on the convert button the file list goes away and the screen returns to the opening page that contains the the file directory. I have re-installed and rebooted with no change in performance. When I attempt to convert by right clicking on the file in windows explorer, I get the following message: "Error running Music Converter." I wold appreciate any assistance. Thank you.
