I formatted my brand new MP3 player as it requested it me to do, after putting in a few songs to test it out, the songs were either not not playing or it plays half a song and skips to the next song. I have formatted it in WMP,FAT, FAT32, NTFS and finally to its default settings but all of these attempts failed. This Mp3 is an unknown china brand i guess, its call Jie Li and thats the only info that came with the player. If there is a solution please help me. Thank you
