Error 2: Your license key has expired.

Cause: Incorrect system date on the computer or the license has expired.


  • If the system date is correctly configured, and you still get that error after a few attempts, the most likely cause is that your license has expired. Renew the license by purchasing a new license key at a discounted price.

Error 3: Your license key has reached its activation limit of the computers.

Cause: You have already activated the program on the maximum number of computers that your license key allows.


  • Please unregister the license on the other computer, then register the license on the computer you are using now.
  • Or you can purchase a new license key for the computer you want to use.

Error 4: Number of phones exceeded.

Cause: The error occurs if you have used the program on more devices than your license allows.

Solution: Check the number of devices in your license details. According to the results:

  • If you have exceeded the number of devices allowed, purchase another license or remove one of your devices by contacting our support team.
  • If you did not exceed the number of devices, please contact our technical support.

Error 5: No internet connection.

Cause: A network connection error may occur when activating our program.


  • Check the network connection on your computer and try again.
