Licence has already been used

Hi Simone,

We could realize that you are referring to AVG Anti-Track activation key.
We would like to clarify that your AVG Anti-Track key has limited activation attempts and can be used only once.
Hence, when you reinstall and try to use the same key, it would show the message as key already used.
We have now made the changes internally and you can proceed to use the same key for activation.
Thank you.

Solve the problem of the key has already been activated, please reactivate the key 
pleas help
