DA:I won't start up after 50+ hours of working fine

The game ran fine for 56 hours but now when I try to start it up it just says DA:I has stopped working. =(

It was loading a scene for a long time (one of the Inquisitor throne scenes), so I closed out of it by signing out of my windows account. When I went to relaunch, Origin downloaded a 77 mb update and Dragon Age: Inquisition stopped working.

When I run it, a black window comes up and it tells me it's stopped working in a prompt and closes.

I've tried rebooting and repairing through Origin but those haven't done anything.

Please any advice to get my game back!
