Hi! First than all, this is working 100%. But i have to say that you have to get a valid serial.
This is not exactly a "crack". This lets you to valid the installation and be able to connect to the server to download the updated for be able to play.
So, make sure you doing right:
1-Mount your image with Daemon-Tool with SecurROM activated and install the game.
2-When installation its over DONT EXECUTE THE GAME, just uncompress the crack into the installation folder and execute the .exe.
3-Its done. Now, execute the game and get a valid serial and write it. Press OK and the update will install some files and when its over, you can play.
I have to say that i have a serial but its expires because too many copys of the game were used to install the game with this serial. Anyway, this is the serial CAA-7CKP-Y7GC-KC9W-URC4 so you can prove what i said is the true.
I haved prove the crack with the demonoid version of the game. I really dont know if another version will be work. This is the link: http://www.mininova.org/com/1522915
