Do you guys even google this things? You need some kind of other .exe that checks online for a key that has been leaked and changes it. Simple stuff.

example
say key 0000 has been found leaked and is stored on your website and your .exe that checks will tell the user the key is incorrect and lock them out of the program until a new key is found or bought.
