Looks like it is something to do with Python3.3 in Sublime Text 3...
After numerous tries to fix this I installed Sublime Text 2 and now able to use this plugin without any issues!
Edit#1: Was able to solve it for Sublime Text 3 by following this guide:
In the Sublime Text menu, go to Preferences -> Browse Packages. From this directory run:
git clone -b development git@github.com:SublimeCodeIntel/SublimeCodeIntel.git
Clear your codeintel cache if you had older version of SublimeCodeIntel installed on your machine, i.e.
C:\Users\user\.codeintel
Restart Sublime Text
