Okay, so I'm to the third chapter of Hordes of the Underdark. Totally kicking tail, having a ball, enjoying the game. I get to the part where you pick up *SPOILER WARNING* Aribeth, and I do so. We're in the icy cave where you first find her, right? So I pick her and the drow chica and try to leave. But my loading screen only goes until there's about an inch left until completion, and then stops. I've tried waiting, I've tried leaving with Valen instead of Aribeth, I've tried all of it. Doesn't work. Always stalls. Any solutions?
