*groan* I don't have my old pc with me, it's an ocean away, literally. Will formatting my MP3 Player and a clean reinstall of Sonic Stage 4.3 help? By the way, I didn't bring anything from my old PC to my new PC (which means, I didn't copy SS from my old PC to my new laptop). My MP3 player is the Sony NW-E005 (green) and it comes with Sonic Stage 3.4 (which works in my previous machine, also running in the Vista OS). I am currently using Sonic Stage 3.4. Is there any other information that you need? I really appreciate the help, by the way.
