Hi, Built the game from source, went smoothly enough bar the 503 errors On getting in game, windows vista 64bit home premium alerted me to a non-digitally signed driver: aken64.sys that was attempting to run, and warning me that all drivers had to be digitally signed, and this driver would not be allowed to run. After clicking OK, the error went away and the game continued, seems to be running just fine. Just wondering what it actually is, and how much of a problem it poses by not being allowed to run? Chief
