Ensure that you have correctly entered your dugiguides website Username and Password in the installer.

Run World of Warcraft Retail or Classic or TBC and check if this has resolved it, if not, I suggest for you to start a ticket here. https://www.dugiguides.com/amember/helpdesk Dugi will investigate further, that way, if there is a payment issue, that will be done privately between yourself and Dugi.
I hope this helps and that you can get back in to the game. Good luck!
