Where can I find Creo 4.0 product code?

I've just successfully installed Creo 4.0 but I haven't received a 4.0 product code. I've tried the only product code I've found, that was in a pdf entitled "PTC Creo 3.0 – University Student Standard – Quick Installation Guide", but this is for Creo 3.0, and obviously, it didn't work.

A few minutes ago I've received an e-mail from - saying "Thank you for your interest in the PTC Creo 2.0 Student Edition. Attached is a backup copy of the license file that was downloaded during the initial installation of Creo 2.0", and curiously, the file attached is for Creo 3.0.

So, where can I get a compatible License File or Product Code for Creo 4.0 M010, which I've just downloaded and installed?
