When a Client of your software changes his system clock either by accident or intentionally to try and defeat the Armadillo protection, the software may stop working and report a Clock Back error.
You can issue a special FixClock key which will fix the clock problem on the Clients computer and allow him to use the software again.
Simply enter the name of your Product (the name used in the Product/Certificate) and press the OK button.
A new FixClock key will be generated which you can send to your Client.
In some situations a FixClock key will not solve the problem and a new Registration Key must be issued.
