When ENUFF PC is installed on a computer, it will display the Reference and PC ID numbers every time an administrator/parent logs in.  These numbers appear on the screen which tells you that the trial period expires in  X number of days or that the trial period has expired.  

Make sure this Reference and PC ID# is taken from the computer you are trying to protect with ENUFF PC ! 

If you still can't find the Reference and PC ID number(s), click on Start, (All) Programs, Akrontech, ENUFF PC, "ENUFF PC". If you don't have a program group called Akrontech in your program list (after you click on Start) then you may need to log off and back in to windows as a different user. If nothing works then download a new 30-day trial from our website and re-install. During the installation, the "Trial period has expired" window which contains these numbers, will come up.
