He's a critical NPC to the game continuance. You cannot skip it. Low memory will do funny things. Reboot your machine, free as much memory (close all background programs)and load your last game and try again like Han said.

I'd like to close by quoting Bellegar's famous last rhyme:

"Cursed be the mother that bred thee!
The wench must have been a hell-spawned banshee!"
