I feel your pain. My hard drive crapped out on me awhile back too. Problem is, most of what I lost can't be reinstalled :( Months and months of work, gone in an instant. Most software companies these days will let you send them your original CD and they will send you another one with a new serial number. I always keep my Serial Numbers in a safe place, but I have had to this with with a couple of games that had the CD-Key on the case ( I have a nasty habit of throwing away cases as soon as i get the cd ). Its a hassle but its the most guaranteed way. Just send them an email telling them your dilema and they should send you a link telling you where to go to get it fixed.
