the mistake most people make is to run the install instaed of first saving it to desktop.
after you save the download to desktop it is yours, just burn it to cd and you have your disk to forever reinstall it as needed. but as
Syxx_Killer said, save your registration key. i have mine written on the cd and on a sticker on the cd case.
but only buy the download if you already have the game and just need to get the v1.5 ad-on so if you havent bought anything yet i would say only buy the gold edition.
