Looks like something's gone horribly wrong. Across all projects, including newly created ones and ones with different kinds of footage, all I'm getting is a black screen in both the Source and Program monitors when using CUDA acceleration. This happens even to titles - everything is black. Audio plays, though.
The weird thing is, I didn't update anything. It was working fine a couple of days ago, and suddenly, boom, nothing. Turning CUDA acceleration off fixes it, but that's hardly a solution.
In my Googling I saw that others have experienced this before, but in all instances the problem was not solved.
Help! I need to edit!
