Dude, just hit the check box that says something along the lines of, "Copy crack content to game folder" when you're about to install the game. They make it easy for you, and it still doesn't get across. Some people man. Paste the files in where ever you installed the game. If you don't know where right click the game shortcut and open file location. If you didn't make a shortcut, and you still don't know where then make use your search bar. I'm going to assume it's somewhere in your program files where it usually defaults to.

It's too HARD for me. I couldn't beat the green dracomage T-T better try the "Story Only" next time :(
p/s: min sys req is "Windows 7 or newer, 64-bit".
