Need product key for microsoft small buisness 2007 (by 2 users)

I have my office small business 2007 cd that I purchased last year, but I can't find my product key. My computer crashed so I'm reinstalling everything. I called and emailed Microsoft but have gotten no response. I am looking at the shinny cd as we type- is there any possibility of the product key being printed really small somewhere on this pretty disc or will it just be the most elegant $260 coaster anyone has ever seen? If anyone has any suggestions or a product key that would work with my disc I would appreciate it greatly. Thanks
