PyMEL not working in Maya2013

I am new to python scripting in Maya and recently after finding out about PyMEL 
I downloaded it and it was working in Maya. Then I set-up Eclipse IDE for 
writing scripts for Maya. First of all auto completion didn't work completely. 
And perhaps after that when I tried to run PyMEL script in Maya it gave some 
errors. And the worst part is, in the output window of Maya's script editor the 
errors keep displaying again and again like in an infinite loop and it is 
stuck. I have to close Maya otherwise that keeps going preventing me from 
working on anything else.

I am using Maya 2013 in Windows7 Professional -64 bit. The PyMEL version I'm 
using is PyMEL-1.0.3. 

I tried running the following code which is to create a simple UI Window.

import pymel.core as pm
window_name = 'Test Window'

if (pm.window(window_name, q = True, ex = True)):
    pm.deleteUI(window_name)

if (pm.windowPref(window_name, q = True, ex = True)):
    pm.windowPref(window_name, r = True)

window_object = pm.window(window_name)
window_object.show()    

It worked before but now I get errors which I cannot track since they keep 
flowing non stop. When I looked closely while the errors were displaying I 
noticed files named apicache.py,setup.py, factories.pyetc. There were few 
warnings about Maya plugins too. 

I tried another script with maya.cmds and that works.Its just the problem with 
PyMEL. I'm not sure what is the issue. Please help. Thank you.

Please provide any additional information below.
