I've been using a backup copy of AG for a while. If you do decide to go down this route, I'd advise taking the DVD out when not in use. Mine has started throwing a disc read error up.. a few other people have had similar issues.. although I couln't swear if they all have burned copies, or if it's a problem with the DVD unit. I've read somewhere that there's a fan inside that is prone to failure causing overheating.
