Problems with Sketchup Pro 2016 Activation

i got the exact problem, i contacted their help but it seems like they are not trying to help but just giving me the codes which i allready got and sending me away to look for help in the forums (terrible costumer service to use that kind of practice and solution to their past clients which payed for a lifetime! licence), maybe they dont know the meaning of lifetime or maybe they really want want to sell your more products and not honor their own contract with their clients.
