Problem to douwnload nXT 5 beta

I cant find my FL 3 lisence number for nxt 5 beta. I have 1,2,5 and nxt versions.

I just emailed the address we had registered for you with the license, email tech@mcneel.com or sales@mcneel.com with license questions in the future for faster help. Let me know if you need anything else, and thanks for testing the beta!
