Hi, I just bought today N-track on SWReg online and received the codes per email, but when I entered the codes in my ntrack, a message box popped out and told me that my registration codes were invalid and were used by internet-pirates and that I needed to contact support.
Did any of you out there had the same problem? If yes, how did you solve it? 
Regards
Carlos
Same thing happened to me. Contact Flavio through the support/feedback form and he will email you as to how to correct this.
