Why do i have to submit my full name and billing addresswhen trying to buy a licence? I have had my personal info stolen before and i am very skeptical as to why i need to provide my details when i pay through a medium like paypal. i would happily pay for a solid software like this, my trial worked with no problems but the fact that i need to hand over all my info is a bit unnerving. are there any ways of billing around this?
