ddraw is Direct Draw, right? Reinstalling the latest version of DirectX should fix it, I thought. Make sure it's the latest version. I'm not sure what the latest version is at the moment actually, but Windows' site shouldn't have anything for download but the latest version.

You didn't get a Windows CDROM with your computer? That's really not good at all. That's something you absolutely need. Not just for reinstalling the whole OS, but sometimes if you add new hardware you need the CD for drivers too.
