Shouldnt need to "apply" for another license. You got one when you paid for the program, which is now yours. It should work on any hardware you choose, just only one hardware at a time. Software that ties itself to the computer is like having your drivers license tied to your first car. Once you change to a new car, you have to do the learners and driving test period all over again. FAIL. I know the author needs to be paid for his hard work, but drop the computer tie in. I hate to say it, but no wonder the program was cracked.
IT'd suck if I bought a book and took it home, read it, moved house, then went to read that book again to find an ugly message saying I need to re-something the book to enjoy it again.
I like the apple itunes setup. You can only authorize so many computers (via a server) to use your itunes account. Once you've used them all up, in order to authorize a new machine, you first must de-authorize a previous machine. Yes its still tied into the machine, but with a few mouseclicks, you can release (your old laptop) it, and then authorize it on (the new laptop) a new machine.
