What's the error...?
And you should always backup the original .exe file, in case you need to d/l an update or a patch. Just make a folder called "backup" (without the quotes), and copy/paste the ORIGINAL exe from the game into there, then copy over the cracked exe into the directory where the non-backed up exe is, and overwrite it. You have to make sure you get the right version of the crack for the right version of the game you have.
