I just updated my graphics driver and Skyrim won't start anymore. After disabling all mods, and manually deleting the EBN dll's, scripts, and folders, it gets as far as the company splash screen before abruptly crashing. Before attempting to figure out how to roll back my NVidia driver (never having done so before and not having any idea what the previous verison was), I want to try a clean reinstall of Skyrim.
I have Skyrim (regular, non special edition) via Steam, along with all the DLC's except the high res graphics pack -- which I also purchased via Steam. In order to promote the Special Edition, Bethesda removed the original edition's DLC's from the Steam store. If I back up my saves, uninstall Skyrim, and reinstall it, will I lose/not be able to reinstall the DLC's since they're no longer available?
