In all honesty I have had similiar problems locating a normal shader here, I found a few older ones that worked, I had to expand my search and what I did find was full of bugs anyway.

I have noticed a lot of people asking this question and being given the same answer...search for it! lol

I think you can find a Normal shader in the Wiki, so If I was you, and you are having the same problems finding any others, use the one in the Wiki

Hope thats a little more helpful to ya!
