Problem with Logik?

Hello. I'm totaly desperate. I've got a Logik 3503 2GB mp3 player. And the thing is that one day after loading some music, something whent wrong. Now every time i try to turn it on, main screen with "MP3 and WMA player etc." text appears , then player shuts down, the screen appears again, and this "rebooting" can keep on going for hours. Maeby somebody had the same issue? is there any chance of fixing it?
