In Windows, I normally reinstall right over top of the old installation and that ‘normally’ fixes it. With something like Daz and the loads it puts on computers and graphics cards, it could be something else. Did you do any OS updates just before this happened? Is perhaps your AV blocking it as it does try to connect to the net?
No OS updates. And what do you mean by AV?
I’ll try reinstalling first though.
EDIT: I Tried, and it still only goes to a certain point before giving up and not showing anything.
