So I have this weapon mod called the soul reaver http://skyrim.nexusmods.com/mods/19436/?tab=2&navtag=/ajax/modimages/?user=0%7C:%7Cid=19436 for link. The modder has a crazy name for the sword and all I want to do is change the name and some of its stats. But I keep getting an error message when I open the mod up in the CK it says "Soulreaver.esp contains a form with a master file ID but no match in the master file.

This mod didnt come with a master file. So when I try and edit the sword it doesnt show its in game model or have its enchantments. Another thing is that his file only came with one NIF file but he has a menu model, a world model, and a firstperson model. How is that possible with only one file? I wanted to rebuild this mod from the ground up or just fix the problem. Please Help!

Edit: Download the soul Reaver file and see what I'm talking about thanks,
