The first time it happen I was basically screwed for months - I resubbed to WoW for a bit because I didn't know how to get an older release of SkyrimSE.exe. I've never seen it take only 24 hours to get things in order for this. Watch the video in sticky of the comments. If it's not possible - you're basically screwed for the next few weeks / months because they have a new sword skin and player home for sale in the cash shop and that was worth breaking the game for EVERYONE. If you didn't, I know it is possible to get one but I don't know how myself. In short, make a backup of your SkyrimSE.exe from before this update.
