 As Ashraf told you, you just have to go Update. To see if you have a validate subscription, you can go SUPPORT, in your Maxisys and you can see the validation of your subscription.

Hi, is it a used tool bought from another customer? If yes, then there is no need to do registration again. Please write to support@autel.com with the S/N of the device and your ID. We will transfer the tool to your ID.
