They do have a crack, I just colored that out.
Please do some research before saying something like that.
It's impossible to crack a pre-release like that without a functional executable.
The only way there would be a working crack was if
A. Leaked functional copy of the game has been acquired by a scene team.
B. The code was compromised.
C. You have a quantum computer capable of performing all the algorithms to "guess" the code.
If you're not BSing, the "Crack" you're seeing is either a trojan, or a crack for the demo.
