Snow Leopard is not supposed to be in anyone's hands in the general public until tomorrow.
If you bought it through an Apple authorized seller, and got it early, wait at least till late tomorrow for others to test it. Inform the place you bought it at that they are sending it earlier than they should.
If you got it from the developer program, purchase the official release and erase your system before asking any questions on this board. There may be bugs in what you got.
