I feel you take a risk from buying from none 'Registered Partners' & even then its worth checking to see if its still the case? For myself, it depends on the cost, I have taken a few risks & mostly been OK, but if its a long term license & expensive I'm very, very careful, to be absolutely sure, buy from the company ideally in sale or accept the risk & don't get to upset if it goes wrong, if a price is to good to be true, it likely is
