i have a torrented ISO of all my games on an external HDD.. even though i own the games, its far easier and faster for me to just download the ripped ISO from some torrent site and install from a virtual disc... then i just type in my legit cdkey instead of using the crack and it works fine
I've done that before. It works great, but be sure to uncheck the crack before downloading so you aren't downloading and uploading the illegal part.
