I have no problem getting into the ruins of Bthalft. I shoot the dual Tonal locks to open the locked gate. However, as soon as I get to door just past that my game will freeze every time.
I've tried verifying game files in Steam. Loaded a previously saved game. I've even tried doing other quests and going back later to no avail. I've been all over the internet looking for a solution. It looks like nobody else has had this problem.
I am playing on a PC. Any help would be greatly appreciated.
Well, first things first, do you have mods? Some of them cause outside issues like freezing at random points.
Otherwise, I've noticed that the farther in I get in Skyrim, the more freezes that occur. I suppose you could try a few things such as telling your follower to wait outside the forge, or try letting the forge sit there for a while until The Ruins Bthalft resets completely to see if that helps.
