No dialog between group and Dar, Hrothgar Options

[Arthalion]

When I try to talk to one of these NPC, they won't say anythin'. For example, when I try to talk to Hrothgar, he will just stand there without sayin' a word.
The game will just say: "Hrothgar has nothing to tell u"

I'm would be very greatful for any response, thank u.

I had some mods installed before the instalation of NEJ. Could this be the problem?
I have the patches and fixes.
The problem occurs right after I visit the inn, where is Hrothgar placed. There is that welcome text, which tells me, that I'm in Easthaven etc.
And then, when I want to talk to Hrothgar, he just stands there and doesn't say anythin. He is in that "dialogue pose" or "alert" pose if u want, but he doesn't say anythin. The game just writtes: "Hrothgar has nothing to tell u" or somethin like that. The same problem happens, when I try to talk to Dar.

Is this specific enough or u need some more informations about the mods installed before NEJ?
