Ok, I'm no lawyer, but to the best of my knowledge, if a private citizen in Sweden owns a set of legally bought floppy disks, they can sell those disks to whomever they want, and that person can use the software on the floppies however he or she wants (even reverse engineer and modify the software for personal use) no matter what any foreign license agreements says. Generally, most foreign licenses are more or less invalid here because of our so called consumer protection laws which grants the consumer some unalienable rights. Floppy disks with software would be pretty much equivalent to a book in the eyes of the law.
This does not mean the software company has to grant the new owner any use of their servers, or customer support (though I actually think they have to honor any guarantees still standing at the time of re-selling).
I realize this could have changed since we joined the EU, but I think I would have heard about it. This is how it used to work in Sweden anyway (and should, in my opinion).
I can see how this could upset Cakewalk people however, so I apologize if that is so and will quietly go away. I'm just saying that I'm not asking for anything illegal.
Anyway, I'm just looking to buy a set of original floppies of Cakewalk 5 for DOS.
