Ableton Lite - I didn't get any emails for it

I read the support thread here:

https://support.native-instruments.com/hc/en-us/articles/360000647317-Where-Is-My-Serial-Number-for-Ableton-Live-Lite

… but I didn't get any emails relating to it at all, so I'm not sure WHAT to do. It took me three weeks to get the firmware updated (nightmare) and now I have no ability to get Ableton.

Is there a link somewhere other than the email that I didn't get? Or some way to get the email re-sent?

Thanks!
