Source is from a warez site, so I don't feel like posting here. Its the same guy who released the previous working crack.EDIT: Steam has been updated and there is some talk about it being patched. It could also be that IW servers are overloaded with players (and pirates), which is causing problems. However, even when IW DOES release a patch for this, dedicated servers are DONE and just being tested now. They should be out by the end of this week!
