Help: Noone has anything to say to anyone

Hi all

This is very strange, dialog in my party has completely silenced, I think it has been that way for a long time. Nowone will enter dialog "charname has nothing to say to you" - everyone.

My party is this:

Myself: Human Berserker, Chaotic good
Minsc
Kivan
Imoen
Branwen
Xan

Im in chapter 5 and noone has said anything for a loong time. What could it be? Ive done quest from a good alignement pov. Reputation is 20 (herioc) atm.

Hell, even Imoen wont speak to me :/

Any suggestions?
