I wish I knew as much about computers as I do the games I play on them, but sadly, that just isn't the case. So, I need your help, please...I'd be forever grateful if you can shed some light on this one.

I downloaded one of the only two C64 emulators that I've found on the net (the other emulator's site was in German or something so I was scared away). However when I try to open it, I get a message saying that a ".DLL" file is missing -- specifically 'D3D9.DLL' is not being found. I have NO CLUE what that's supposed to mean, nor do I have any idea of where to aquire this .DLL file. Heck, I don't even know what a .DLL file does!

So if anyone has any information as to what I'm supposed to do about this, I'd be unbelievably grateful. I was just so excited when I realized I could play all of my old favorite C64 games again, and once I hit this road block, I felt so disappointed.

Thanks so much for at least reading this.
