Product Licence Key

Good Day,
I purchased a Mixvibes FirstMix USB Powered Table Controller S/N DNxxxxxxx which came with a Mixvibes Cross DJ LE 2.0.2 Installation CD. I have since lost the paper CD cover that had the product key printed on it but still have the Installation CD. I did not register my key on your website.
Please help.
Regards,
Malik
