2GB microSD not responding

[bdube]

As a follow up, I had a Sandisk 128MB card I inserted. In Windows MediaPlayer, it let me sync a playlist and looked like everything was fine. I removed the player, restarted it and although there was no lag, it couldn’t see any playlist or music at all on either the internal memory or the 128MB SanDisk card. I removed the card and mysteriously all the internal music now shows up and plays. The playlist and songs copied to the 128MB card play and work fine, just not in the Express player. So I now doubt it has anything to do with the Kinsgton 2GB card since I’m getting, not the same, but a similar problem with SanDisk’s 128MB card. I say not the same because I can’t even sync the Kingston card while it’s in the player. The Sandisk card will sync while in the player, but it’s useless since with it installed the player can’t see any of the music on it or in the internal mememory.
