MP4

I BOUGHT THIS MP3/MP4 PLAYER ON EBAY AND I HAVE NO IDEA HOW TO TRANSFER VIDEOS OR SONGS TO IT. THE DISC THAT THEY SENT WILL NOT WORK SO I WENT ON THEIR WEBSITE AND DOWNLOADED SET UP FROM THERE (IT’S IN CHINESE) BUT WHEN I TRY TO DOWNLOAD SONGS I GET A MESSAGE SAYING DIRECTORY OR FILE CANNOT BE CREATED. I’M NEW AT THIS, I HAVE NO IDEA WHAT TO DO SO ANY HELP WOULD BE APPRECIATED.
THANKS

get it replaced the memory is duff
