Decided to try a few things out of desperation. Who'd have thought that changing the resolution would result in it automatically changing the default profile and making it unable to select any other profile..
I understand the devs are busy fixing bugs and whatnot, but is a simple acknowledgement of this problem that's affecting so many people too much to ask for?
Almost a month after release and it's starting to feel like a big waste of money, which is sad because act 1 was fun to play.
