nltk Stanford Segmenter : NoClassDefFoundError: org/slf4j/LoggerFactory (Windows) - nltk

Question

I'm relatively new at this. Trying to get Stanford Segmenter to play well with nltk and keep running into this error I havent been able to resovle.
This is the error:
CRFClassifier invoked on Tue Jan 19 17:39:25 CET 2016 with arguments:

Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
I have python3.4
I've reinstalled the nltk (current version 3.1)
I've added the classpath of the slf4j-api.jar (any other .jar i need to add?)
import os
javapath = "C:/Users/Documents/DaimText/stanford-segmenter-2015-12-09/slf4j-api.jar"
os.environ['CLASSPATH'] = javapath
Still doesn't work. Any ideas?
Thanks alot!
UPDATE:
Uninstalled: stanford-segmenter-2015-12-09
Installed: stanford-segmenter-2014-08-27
Followed the test code from here:
http://textminingonline.com/dive-into-nltk-part-vi-add-stanford-word-segmenter-interface-for-python-nltk
Works!
Seems like it might be a problem with the new version.
