How can I get Soundbooth back to work on my new iMac?

A while ago I managed to download Photoshop CS on my new iMac computer, which worked fine, as well as Soundbooth. Then out of the blue, adobe asked me for my registration number in order to use Soundbooth. I only had one number, but it was no good (anymore).

Because I needed to work with Soundbooth straight away, I chose the option to use a 30 day trial version, that has now expired. Whenever I try to start up Soundbooth, I am reminded of this, and my registration number is still no good.

I need to work with Soundbooth real soon, I own this product, but I seem to have lost the possibility to get access. Please help me out here!

Thanks,

Gerrie
