Sandisk C-150 2GB MP3 Player

I have the Sandisk C-150 2GB MP3 player, and I can’t get it to load songs. It says the device is no longer responding or is disconnected. I have the USB cable plugged into my computer, and every time I try to load a song onto it, either by drag and drop or copy & pasting it, that’s what pops up. What do I do to fix this? I formatted it to see if that would fix the problem, and it didn’t fix it either.
