Incorrect Activation Code For Machine ID
The Activation Code that you entered may not belong to this machine ID. Each Activation Code is generated based on the unique machine ID that Smaart generates based on your computer specifications. Verify that you are entering the Activation Code that was generated for the machine (and specifically, the ID) you are trying to activate.
Note: the Smaart Machine ID may change if you reformat or replace your hard drive, re-partition the hard drive, or re-install the Operating System. The new Machine ID will require a new Activation Code.
