I've more or less accepted I'll have to relinquish my daughter's program because she will need it for the laptop that replaces the one I loaned her, but how do I legalize/pay for the download from the link you've suggested?
I've had a look at it and of course it's asking for the key as per normal.
Amazon seem to be selling keys/booklets, but they are virtually the same price as bigger packs. Nothing seems to make sense on the pricing of these things.
