It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

Problems: game freezes randomly, crashes on *every* cut scene, can't save any of the settings, can;t play in windowed mode.

I am running Geforce 580 GTX, Intel i7-2600, 16Gb RAM, 1920x1080 rez, nvidia driver version 337.88, MS Windows 8.1, dual monitor setup, Razer peripherals.

I am running it as administrator, I am having best luck when I run it in Windows XP Service Pack 2 comp mode.

Any tips ??
You might want to submit that as a support ticket, if you haven't got it working yet.
