Way to retrieve lost Serial Number for Sony Vegas Movie Studio 6.0? - retrieve sony vegas 6.0 serial number

I bought Sony Vegas Movie Studio a year ago. I installed on a computer, then lost the box and the serial number. And now I want to install on another computer, I can not because I do not know the serial number.

I did not register the product, so there is a way to send the serial number? Any help is welcome.
