Installation error

Hi, I’ve been using D5 Render PRO for 2 months. I have now updated my computer and am trying to install the program from the official website, but the installer is not downloading. I managed to install D5 launcher using your link above, I logged into my D5 account, but even through this launcher I can’t install D5 Render. I don’t know what to do anymore, and I really hope for your help in this matter.
