How do I reinput an activation code?

Hi,
Ive just bought a new laptop, and I have a few questions:
1 I have mixvibes installed on 2 laptops now (I got rid of my macbook (clean install of mac os so got rid of the old version) and bought a new super sweet windows laptop). How can I confirm Mixvibes has registered that I have two laptops registered?
2 I think I have accidentally inputted the mixvibes home activation key rather than the full version (I took it from my account and have two there and may have messed up). I only say this as I only have one input working on my soundcard.
looking for a quick answer
