Arduino dont works

Hello

I bought my Arduino last week from the website, and its taking some problems. When i use the "Button" program, by clicking at the button, the board shuts down, and the Serial Port disapears and i was testing in other computers and ask for help of technical assistence and it seems the problem comes from arduino. So i want to know if its possible to send the arduino back, to fit. It's very urgent.

model:Board Model UNO R3 serial number:A000032 version of the operating system: Windows 7 version of the Arduino software: Arduino 1.0.1

It sounds like your button is providing a short-circuit, but without more details it is hard to say.

Where did you by the device? have you contacted the vendor?
