Is it safe to download Microsoft office XP pro from limewire? What about a CAD CAM Package?

I would highly recommend that you do download that file. Your reward for attempting to steal that from Microsoft will be a ton of malware that will totally screw up your computer. As long as you don't mind being a thief, why not just walk into a store and stick it in your pants. Same thing, but it sounds like you enjoy a challenge.
