I had no problem installing it but for some of my accounts, if I speed up(Time ×2.5) in map mode, after a while, the game will stop running. So, I loaded the game again and same thing happens. I tried for many times but it still couldnt work! It kept saying, ".ENGINE has stopped running." Then they just say that windows is trying to figure what went wrong but I just clicked the × at the top right corner of the thingie and started another account.
