When you downloaded Amplitube 3 how did you register it? Everytime I get to that page it's requesting a serial number to input? I didn't receive any such thing while downloading that program. Did you?
Did you have to create an account when you downloaded it?
I already have an IK User Account so I just downloaded it from there - I can't remember what happens with a fresh installation.
If you have an account, you'll have to sign in and navigate to the User Area, then select the Downloads link. The serial should be listed there.
If you don't have an account, I assume you'll have to create one.
The authorisation screen appears everytime you open Amplitube I think.
