Sandisk express

I bought a sandisk express on july 24,2007. It worked fine,But when I went to charge it, It wouldn’t charge . It doesnt even turn on now.Does anybody know what could be wrong with it?And will sandisk fix it?If so how do I get a hold of  sandisk.

                                                                                        THANKS SO MUCH, Mechial

                                                                            

Try the reset of volume + and select (Gray square) at same time… then try turning it on or connecting to pc.
