</3 Doom 2!

I found a website where I could download a copy of the game Doom 2. I downloaded it, and extracted it with WinRar. When I try to run it, however, I get this: http://tinypic.com/view.php?pic=4qsrudt.

Any ideas? I've already extracted to another place, and retried, with the same results.

*EDIT*

I downloaded DOSbox, and tried to run the program using that, since apparently, Windows XP is lame about its DOS... :/

It didn't work, though. :'(
