so out of paranoia, i have started backing up the data on my computer game discs online in case the discs break. (i PAYED FOR these games.) now, one of my discs broke. so, i downloaded the data, and mounted it on another disc. yet, when i try to instal, it goes half way through, tells me to insert disc 2. i insert my copy and it doesn't recognize it. so i am looking for a work around.
