Seems like other people were having problems with it too, but mine worked perfectly, the extraction and importing worked perfectly.Thats the one I had. I have Windows 7 also. It was also giving me runtime errors when I tried to extract certain things. I couldn't get the master chief or any weapons for some reason. Post it here and Ill see if it's the same one I have.
