Ok, i had some problems with mods before and my problems were when I had these errors that:
-some mods were conflicting (maybe you need to merge some files)
-I needed other stuff installed (check the requirements)

Maybe you can better ask this stuff at the site of the creator of the mod. They are more experienced in this stuff, search their forums etc.
