To answer your question you sent via PM, just because a code is in a legitimate format (green ticks), doesn't mean it will authorise the software. The activation codes are likely linked to the initial serial number, and possibly other things to (such as account email address, machine ID or mac address etc), and looking at the error messages you get, also need to be confirmed via the developer's server.

If the activation code matches with your serial number (which it won't) and also checks this is valid online (which it won't be, as your account doesn't have a record of this purchase), then it will activate the software. Even if you guessed an activation code, in the correct format, which (unbelievably unlikely) also matched the hash of the serial number and email address of the account (however they have implemented this), if those things can't be confirmed on the developer's server, you don't get an activation.

You could generate a hundred million "activation codes" with a legitimate format, without a single one activating your software. My advice, if you want this particular plugin badly - buy it in a sale for $49 or whatever it was, or switch to the PC. You're really wasting your time by manually guessing activation codes. Seriously.

To answer your other question - no I don't hate you. I'm trying to help you to not waste your time, believe it or not.

 

I really appreciate your answer ! It has really helped me
