I just bought Scrivener for Windows but I can't find my licence code

I used Scrivener on Mac for quite a while, but then switched computers and bought Scrivener for my windows. However, my email doesn’t seem to have my licence number. It has my order number, but that’s not the same thing, and whenever I do the “lost licence” thing, it sends me the same email which doesn’t seem to have the number.

What do I do? Am I missing something?
