Reactivation

I’ve had to reinstall WaveLab LE on a new computer and in order to activate I need to request a new code. When I press the
“Reactivation” button, it takes me to a page to enter the new code - but where do I find the new code? It is not appearing anywhere - not online nor in an email. I’ve referred to the reactivation info on the support pages and the information I need to find this new code is not located there either.
