[Solved]Demo crashes to black box

[gamgam2]

Un-install the demo
Look in your penumbra file on the c-drive(or whatever drive it installs to) and if the foulder and make sure it does not exist.
Re-install the game

Please post your computer specs also, your computer might be too old to run the game. (Btw, I belive you can right-click on the game-icon and go to properties, there should be some settings in there that MIGHT help you)
