Bosnia, When you installed your mod, you did make a copy of your DFX and install the MOD into your copy? It probably doesn't help with the problem you're having but I was just courious.
What objects are missing ? Are the missings objects from the original DFX software?
Try installing this file :
http://www.dfbarracks.com/downloads/...ion=df&fid=296
This file may restore the hidden files and (if you have never used this file before) it will add hidden item files.
Let me know how this works out!
