Hi, sorry for the late reply.
If any changes has been made to the system clock since you installed Ad-Aware then
Ad-Aware will produce the error message
This is a security measure built into the program to protect the license.
A user should not be able to change his clock to get additional time to his license.
You need to contact support through the Support center and ask them to send you a fixclock key.
If you have lost any time on your license because of this problem, please explain what has happened in the email and they will compensate you by adding on the lost time to your license.

2. When starting up Ad-Aware and the error prompt shows, press and hold the shift key and
click the OK button
3. Enter the Fixclock key included in the e-mail sent to you and click OK
