EULA or not, the laws of most of the world still essentially state that if something does not work as advertised, then it can be returned. Given a dislike for giving money back, perhaps an attorney would be called for, so I will retract the "simply". Otherwise, the rest stands. Thank you for the information.

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
