i have a 1gig sylvania mp3 player (smp 1002 ) everything was working fine, every couple of days i would add a few songs. I have maybe 25 songs total. Then one day i added 3 songs but they will not play. I reconnected the player to the computer to search the files and they were on there. all the other songs play fine, but when i jump songs to get to the new ones it just continues in a loop through the old ones. I even connected the player to another computer and played the new songs, no problem...any ideas.
