you could just stop trying to pirate it and buy it for like $5.
I can't find it in a store*
Ass.
Have you tried EB games? There's always at least one in the preowneds at the ones that I've gone to. Heck, the one I go to most often has an unopened game of the year edition. I really can't see how it could be hard to find DX unless you're looking at someplace like Best Buy that doesn't carry games older than a year.
