Sorry to be such a nuisance, but how do I do that ?

When I know, I will try

Okay so I tried the experimental build, but I just get the blue screen of death all the time instead XD

it's the 0.9.8 version

So I tried the demo, I thought damn this game is awesome. So I purchased the Aplha version, however everytime I try to boot up the game I get a message that says: "C:/Program Files\Factorio\data\base|graphics/entity/acid-splash-purple/splash-4.png" couldn't be loaded I run it on Windows 7 ...
