I'm working on a mod restoring Winterhold to it's pre-Great Collapse glory. I've taken the .nif files from the Imperial Dungeon kit, and changed the textures to the ones used on the College of Winterhold. Then I duplicated the static objects in the CK's Object Window, and I changed the Model File Name entry to the location of the new .nif. I get the following error:

MODELS: Could not find model

tdkNW\meshes\architecture\NewWinterholdKit\winterholdextbldgstraight01.nif

The second line, obviously, is the path to my new .nif within Skyrim's Data\meshes folder. Thanks in advance for any help you can provide.
