One thing to note. Before I travelled to Brynnlaw, there was an error in my dialogue. It said something a like "Nathaniel looks at you, and then you turn look back"-thing. Didn't write it down. But the notable thing was that after i clicked "next" there was a red line saying something like "No dilalogue or links found for Nathaniel". Unfortunately I didn't write this down either

My question is this: What is wrong? Is it fixable by any sorts of codes? Please note that I dont know any of these types of codes by heart
I started a new game just because of this mod, and when I browse these forums I encounter a thread which goes in the style of: "Ive done this now, is it safe to go to spellhold?" If I had known that there were things I had to do before I went to spellhold, I would have sought help here alot earlier. But I saw no real reason for alarm, as I could not find any mentions or tips about it in the manual.
Waiting anxiously for a positve response. Excuse my poor English
