You made some textures and normal maps, and you used them in a mod. When you tested today, everything in the Tamriel worldspace looked fine; but when you looked into an interior ...[please rephrase this part here]...[something about textures turning black]. All textures? Just your textures? You were kind of hard to understand, there.

In any case, perhaps this will help you: http://cs.elderscrolls.com/constwiki/index.php/Retex_Troubleshooting. Good luck!
