If you can't afford to buy a copy of MS Office, use NeoOffice. It's MS Office compatible and FREE. It's a download, too, so no CD issues, unless you just feel like burning a disc. This board is not actually to help you figure out how to use something you pirated. It's not to solve problems that arrive from piracy. It's actually for Mac-related issues, specifically those of the MacBook/iBook variety. As you said, it's not the machine's fault... so this might not be the place for your query.
You may not want a lecture on piracy, but I'm pretty sure talk of piracy the use of unlicensed software is a TOS violation *on this board,* so while you might not like it, it is actually a valid point. It's possible the person was trying to truncate the discussion before a mod got involved. And getting worked up about someone being holier than thou while using a self-righteous tone (and coming from a morally questionable stance) is pretty laughable to begin with. Pot, meet kettle.
