Game won't launch anymore

[SoUnreal]

Happened after I changed my resolution in-game, now I always get this error when trying to launch

"** GLW_CreateWindow: could not register window class

I've changed my resolution from the browser settings, but I still can't get the game to launch and don't see how to put it back into browser mode.
