I would ensure that your username and password is correctly entered in the DugiGuides Installer and try downloading / installing the guides again and then check if that resolved it. If not, then I would log in to the members section on this website and checking payment info and subscription status. If that is not the issue, I would at this point create a ticket, outline what the problem you are faced with and the steps you did from this forum post and Dugi can then look at things his end. I hope you resolve this soon. Good luck!
