I've been playing this for a year on GOG and now it crashes at start. All I can gather is that Bethesda made an update and now GOG is unplayable with mods, and it sounds like Steam isn't much better. I've spent more time troubleshooting than playing the game. Time to give up on Bethesda games for good.
I've been playing GOG Skyrim for a year and after the recent Bethesda update, the game crashes on start. This game seems more like a scam at this point. It's not worth playing without Nexus mods and now it doesn't work with those mods, or it doesn't work at all. I've spent more time trouble shooting the game than playing the game, and that's when it was working at all. Now it just doesn't work.
