feko free licence expantion

Hi
I have downloaded Feko free trail which is 45 days and it has expired I want to have the free trail again, the way I got my previous licence was by installing the feko free program then sending a certain file from it after installation to the company and they sent me the licence after checking the file I have sent them
I wonder if I download the same program again and send the file to the company will it have information that I have already had the licence, mostly i think yes but if any body has another opinion or experience wish he can please share it with me
thanks in advance
