Sound file not found: data files\sound\nm\r\asm_none.wav

I too don't have nm file. Its not in vanilla morrowind so it must be added by a mod which brings up the question what mods do use? Did you install them correctly?

Since it's not a vanilla Morrowind issue, I asked that the topic be moved to the Mods section so we can better help you. Welcome to the boards, BTW! http://images.uesp.net/c/c4/Fishystick.jpg.

I also do not have an nm sound folder, which already eliminates several hundred mods from the equation. Could you please post what mods you're using?
