I downloaded this app which converts DRM to mp3: http://www.ahamediasoft.com/. I only needed it for one song so I erased it right away. However, it uses the "virtual cd" feature and everytime I restart/turn my MacBook on it asks what to do with the CD (burn or open Finder etc the usuals). I check my Disk Utility and erase that "virtual cd" but everytime after I restart or shutdown it comes up. How I do delete this "virtual cd" thing permanently so it never has to come up again? TIA.
