Sounds like your reg keys for resolution may have gotten knackered up buy unclean shutdown. This happened to me a few times, usually after one of SE's updates. I have to go into SE's config, set the resolutions from the drop lists, make sure it is fullscreen, exit/save, then log all the way in then out one time via SE's launcher. After that, I can change the resolutions back for my 1080p and it launches fine.
