Once you unzip the file you gotta click the new unzipped file and select the file until it shows you like a MILLION other files, just scroll down until you find a file that says Clangen.exe. Then once selected for the first time, it will say its a virus, but once you select more info there is an option to open anyway. Also, every once and a while it will kick you off the game, so remember to SAVE OFTEN. I hope this helps.
