Losing your activation is not all that bad. I formatted the drive on my laptop once and forgot to remove all my keys. I thought I was in "big" trouble, but one phone call to A/B tech support took care of it.
Also, a co-worker of mine was installing RsLogix in his new laptop when he realized he had misplaced his master disk. A/B sent him a replacement master disk for his software. Along with the new master disk, was a request from A/B for him to write them a letter explaining why he would not be returning his old master disk. He wrote "I will not be returning my original master disk to you because I lost it"
End of story.
