I bought a generic mp3 player that I had trouble with on all three of my pc's: Win98SE, 2K, and XP. I got it to work using the steps below. You might want to try them. Good luck.

---------

Windows 2000 fix for "Mp3 player not recognized". It asks for a file named actdisk.sys, which is not on CD Rom that came with my Mp3 player, and no information is available about it in the manual.
