Hi there. I'm trying the game out for the first time, and I downloaded the version whose files are dated Feb. 15, 2015. Setup.exe just runs but does nothing, staying resident as an unkillable process (or, more specifically, three separate unkillable processes linked to each other), forcing me to reboot the computer to get them out of there. Not sure what I'm doing wrong. Running Windows 7 64-bit.
