Hi, Domenico,
I looked up your email address to find your account and what I found was that you have already registered this product twice before in August and September of this year, if you wish to register the product on another machine then you can visit your ClickAlgo account and remove these licenses so you can register new ones.
https://clickalgo.com/manage
I think what happened was that you registered the market status indicator instead of the market signal indicator, so the system thinks you have already registered it, again, this is an easy fix, just visit your manage license page, remove both of these licenses and register both products again, make sure you chose the right product.
Let me know if you need more help.
