Yeah, I guess the only ways to get it now are semi-legal at best. Someone might sell their copy or you could try P2P networks. But that is something that shouldn't be talked here since it's not exactly legal to do either.
A recent legal ruling has shown that it is legal to sell software on (under at least some circumstances) regardless of license 'restrictions' in this case revolving around Autodesk
I don't know whether it has been tested in law anywhere yet, but common sense and practice suggests that someone could sell on software that they own as long as they include all the physical media and they remove it from their own computer (i.e. it is fully transferred to the new owner).
Filesharing or Bitorrenting it is a definite no-no though.
