The game boots up just fine on my main rig (http://pcpartpicker.com/p/HGXvpg) but it fails on main secondary rig (http://pcpartpicker.com/p/GD6nbv) I've tried changing the resolution to 640 x 480, moving the installation to the C drive, setting up compatibility mode in windows 8 and 7,launching directly from the executable, reinstalling thegame and DirectX. Both of my rigs have an SDD and a HDD, the games are stored on the HDD.
