it should answer all the questions and save cakewalk going over and over the same ground. it pretty much covers everything you need to know. well done cakewalk (perhaps a little late) it was pretty much what i had thought, but it's good to have it all in one place in black and white for all. the only confusion i found was in my haste to hit the 'buy' button after reading the emails i don't think there is any doubt that the lifetime deal is an exceptionally good one, it's as they say a 'no brainer'
