Query: Problems with folders

I am having the same issue as others have reported where if you have more than 15 or so folders, the player will display all the folders as empty however if you look at it as a USB device in Windows, all the songs and folders are. I called SanDisk support and they determined it was an issue with my particular player and shipped me a new one but it is having the same problem as my original one. Has anyone had any luck with SanDisk support?
