I have installed the game but am having a lot of trouble getting a no dvd crack to work. (i cant find one). Ive found instructions using daemon tools and alcohol 120% but they seem too advanced for me and I am having trouble even getting those to work. Is there any actual patch or NO dvd crack that I can get. If so where can i get it and how do I install it. Thanks any help would be appreciated.
