I bought Motion 5. I have already downloaded it on 3 computers and I know that you can only download it five times before purchasing it again. I will be using someone else's computer soon for about a week and I was wanting to be able to use Motion 5 on it without using up one of my downloads because he will just delete it afterward. Can I copy the program from my mac to an SD card onto his mac? Would that work and if it did, would it count as one of my downloads?
