Where is the Serial Number?

Hi!
Searched the forum but still haven't found the answer to this.
I have a first mix i/O Gemini Controller that came with the MIxVibes CrossDJ LE software.
I want to update now but can't find my serial number that's requested.
1) Where would I find it?
2) Is Cross DJ LE the same as the free version I can download via the App store or website?
Thanks
