Neurolab // "No module named .."

[FiveHydroxy Tryptamine]

Hiya
A word of warning, I am a complete beginner.
My problem goes like this:: I've been trying to "import neurolab as nl"(a neural network library)and I keep getting the "No module named.." error in my Python 2.7.3 shell. There is definitely something wrong with my Python path, although everything looks fine (to me). I also appended the sys.path with "C:/Python27/neurolab-0.2.3/neurolab" and I still get that error. What am I missing?
Thanks.
