Online Registration

I have purchased a Cubase 7 Artist version software which I received by regular mail as a box containing Disks, Manual, a USB key, and essential product license information. Everyhting works fine and I have activated the permanent license using my 32 digits code written on the essential product license information. However, to register the product online a 25 digits code seems to be required. I don’t have that, and so cannot register, neither up-date or get e-mail support. Do somebody has a solution to this issue? Thank you in advance. Gilles
