Hey guys i'm pretty new to arduino but have been working endlessly on this tutorial: http://www.instructables.com/id/Twitter-Mention-Mood-Light/step4/Python/
So i am not ready to give up.
I think I may have installed all of the packages for python successfuly but I am not too sure (is there anyway to text)
I've worked my way out of most of the problems im facing in creating this.
These is the final problems I am experiencing them and i'm all out of ideas now.
Please help 
This is my error codes (processing):

And these are the errors on python:

I know atleast one of the buttons are working as it sends the signal of arduino msg: #peacefulGlow
to pyhon when running module but as soon as the button is pressed then error messages appear.
My LED is not lighting up at all 
I can send pictures of the circuitboard if needed.
Please will someone help me with this.
Either contact me here or and email to broadleyutb@googlemail.com would be great
Thanks
