No, downloading Arena trailer videos and dashboard themes won't "screw up" your XBox. You don't really need a keyboard. The official one is a little mini thing that clips onto the bottom of the controller. Any USB one works. See, that's what we spent a dozen posts going back and forth asking. Microsoft points aren't copies of Arena. With the "coaster" you were implying you had the game on a disc and dodged the question when we asked. Anyhow, nobody should need your point cards to get Arena. Every Crius.net member with an XBox should already have it. If someone was too cheap to spend $10 to buy the first new Wing Commander game in nine years, I'm sure as hell not sending them $20.
