Nothing works anymore. Don't even know where to start
I've been busy the last few months, and probably haven't used my DAZ Studio 4.5 for about three months. I opened the program today and--shock, horror--nothing works anymore. My models are corrupted, files won't load, shaders don't work, and the program crashed when I tried to save something.
But... I've changed nothing on my computer (PC Windows 7). I haven't installed new software.
I don't even know where to start fixing this. I've got a fair bit of purchased content. I'm pulling my hair out.
