I had to get a new activation code because I had to get a new machine. Now, I got an email saying "enter the activation code or copy paste it from this email". But there is no activation code in the email. All I see in the email is product key, serial number, request code.
I think the activation code should be also stored somewhere on the computer but I can't find it (I'm using AutoCAD for Mac 2011 and got mac osx 10.8.2).
