Started with searching all text strings for Unregistered then placed a BP on the first call prior to the badboy at that location
Some strange string is shown
A little further down there is a loop which reiterates the characters in the correct order to give the password
The password is : find_me_if_you_can
It was a good exercise for a newbie like me thank you. I realise that patching also achieves the same effect as registering but for some serial fishing is another option. As the great Lena 151 always said "There are many ways to attack a target"
