I downloaded all of the preload files then moved them from my c drive download file to gog file in program files on c drive. I downloaded latest patch (after file 7 today) and put in the C drive file. When I go to run it says installer files missing. I went back to Gog.com and hit the galaxy button and then clicked download of the game, it is re-installing the game to my c drive outside of the program files and at the rate it is going 1mb second it will be 2 1/2 hours before done to see if possibly works at that time.
