hldj.org

I don't understand the term OS. But it doesn't occur when I go into setup, only when I press play.

I downloaded the build and it worked for a while until it started crashing everytime I hit play. Dang... I hate having crapware. x.x
EDIT
I can't play it on another computer because this is the only one I have. :\

I am currently using the latest version, not the build. Would it be a good idea to download the build?

Well, HLDJ crashes every time I hit the play icon. I do not have IE8 and have already read the sticky. Someone kindly tell me how to fix this.
