Getting Music from WMP to my e260

No I was not in MSC mode because when I tried to put music on it  there was no folder for music. I tried creating a new folder but I could not play the music on the device.

 I just had  this problem http://forums.sandisk.com/t5/User-guides-Firmware-Software/Firmware-problems/m-p/228362#M4014 . last night I tried formating it from WMP even though I was told not to, It "almost bricked "  however I followed the steps again to unbrick it.  That worked so I tried putting music on it again, and I got the problem that I said at the start of  this topic. 

What do you mean by trying a different chord?
