This morning I got back into Skyrim. I deleted all my mods (aside from some essential ones like SkyUI and the script extender), and then reinstalled some of them, along with a bunch of new ones that I liked. So I went out to eat, and when I came back, it was working fine. I go off Skyrim to download a few new mods, and sure enough, the game crashes every time I try to play. So I uninstall all those new mods I just put on, and it still keeps doing it! So I uninstall all my mods. Then I get the message I need to update skyrim.
The problem was, I uninstalled the script extender, which required something in the skyrim data folder. If you uninstall that, then the game will react as if it isn't up to date. HOWEVER my game still keeps crashing, and all I have is sky UI and the script extender on. Anyone know how to fix that?
