Yes it is legally posible. Every once in a while I see requests for version 2, while access to the older software is not possible, you can overcome your lack of internet issue easilly. I don't have internet in my SIM shop either.
Just download and install the most recent version, then make the donation via paypal or C.C. (was $40-50 us dollars in the past) and ask to receive an offline key for one PC.
Well worth it, works great for users like me who have no afordable way to get good internet at home.
The info on this optuion on the web site isn't laid out as clear as it could be, but its there if you look close.
Hope this helps.
