HP 530 Product key support

Question

I bought a new HP 530 on 2008.05.13 and it came pre-installed with Windows Vista and MS Office 2007. Everyting is working perfectly except the MS Office keeps asking for a 25 character product key to input, which I do not have, not in the box not anywhere.

CAN SOMEONE PLEASE HELP ME???????

THANK YOU IN ADVANCE
