Step 1: Check what all records are controlled by the player. How can I access my music? Clearly, it is still on my computer somewhere since I can play through Windows Media Player. Not having access to the original files, I can't add music files individually to my mp3 (Windows Media Player lets you synchronize files only, and I don't want to lose a part of the 'missing' files I have on my mp3 using the Sync feature). Looking for songs via the start menu or through my computer does not work. In Windows Media player, if I click on a song and 'open file location' need me for my music, and the file is not there. I can view and listen to the music of 'missing' in Windows Media Player (library).
