My sansa won't let me play songs! every time the menu of languages come up

Every time I try to start my sansa it takes forever, and the menu of languages appears, I already set that, but I click on English and then it goes to the main menu, I click on songs, try to play a song, and it starts itself back up again, I can't turn it off, swithched it MSC mode, no help, plugged it into the USB, no help, Try to add more songs, No help, PLEASE IF YOU HAVE ANY IDEA WHAT I SHOULD DO IT WOULD BE GREATLY APPRECIATED!!!!!!!! thank you in advanced!!
