My MP3/MP4 player keeps coming up with 'Format Error'.

[elliot22]

It was working fine and I downloaded about 50 songs onto it (it is supposedly a 4GB mp3/mp4 player. I got it off ebay for £30 from some bloke with 98% positive feedback.)
Suddenly, new songs I downloaded wouldn't play.
Everytime I try to play them it comes up with 'Format Error', then it usually turns off my mp3 player. According to the memory, I have only used 6% of the memory.
The songs that aren't working are in the same format as the songs that are working.
Can someone please help.

Thanks.

elliot22 , it seems that your player memory was hacked. Try the formatting guide here http://www.mympxplayer.org/how-to-re...ck-vt2400.html
