I'm trying to get a classic graphical adventure game called Discworld II: Missing Presumed to work and i have downloaded the DosBox thinking it could help me play it, because when I load up the game, the developer and publisher logos appear as usual, but when it gets to the title screen, the picture appears, but suddenly blacks out with a message appearing, saying "Direct Draw, cannot do something-or-other with DirectDraw services" or something like that, heh.
I figured this had something to do with the fact it wasn't running on an MS-DOS-based machine (I got Windows XP). Could anyone help me? The tutorials in the Guides section are confusing and speak of login names and stuff like that....

I downloaded the very first downloadablre choice on the website's Download section (windows).
