Well, good question. I actually never played the english version myself and it's about 10 years or more since I've last looked at this mod. It's possible that you aren't using the latest english version, but can't check, as it apparently isn't on NMA anymore. Moddb says 1.1 while german is 1.3 - that's weird too. It's really possible that I never updated the moddb file version. In any case you can progress without talking to him *right now* - one of the NPCs can lead you to a cave (the bartender? or a drunk). Go there.
