if your relative path is exactly as you wrote it, you should replace the forward slashes with backslashes. Nifskope is smart enough to ignore that typo, the CK and game however are not. Edit: Also, as stated above texture sets are the most llikely reason for other textures being loaded. I guess you tried to overwrite a vanilla mesh, instead of making your own record?
