oops... Too much information ;-) ...missed my double copy of the traceback!  
The Service Account that was disclosed has been deleted.

Try upgrading to Python 2.7.5 and see if that helps:

Upgraded to Python 2.7.5 (verified the by the banner);  Set up a new service 
account and authorized it in the domain admin panel.

New error message:
Traceback (most recent call last):
  File "gyb.py", line 1011, in <module>
    main(sys.argv[1:])
  File "gyb.py", line 492, in main

  File "gyb.py", line 187, in generateXOAuthString
    credentials = oauth2client.client.SignedJwtAssertionCredentials(service_account_name=service_account, private_key=key, scope=scope, user_agent=getGYBVersion(' / '), prn=email)
AttributeError: 'module' object has no attribute 'SignedJwtAssertionCredentials'

The problem is caused by the following code in oauth2client/client.py

886 if HAS_CRYPTO:
887  # PyOpenSSL and PyCrypto are not prerequisites for oauth2client, so if it 
is
888  # missing then don't create the SignedJwtAssertionCredentials or the
889  # verify_id_token() method.

Basically you only need to install PyOpenSSL and PyCrypto (using easy_install) 
to fix the problem. It would be nice to get a more useful error message though.

In case someone faces the same issue as me: This guide helped me to install 
Python 2.7.5 along the repository one:
http://www.bango29.com/go/blog/2013/python-2-7-5-on-centos-6-x

In case you face errors at this
$ python2.7 setup.py install
step, make sure to build python with the needed modules (the error tells you 
which, I forgot some ssl I think). After that, when easy_install works, just 
install pycrypto and pyopenssl and all works fine

I didn't use python, as I'm not an expert. But whenever I got to the permission 
page, the "accept" button did not work. So I followed instructions to add 
"nobrowser.txt" to the c:gyb directory & tried again. Same results. No response 
to "accept" button, thus no verification code to enter at CMD prompt. I'm not 
in a position to even begin to understand the info added above. But this item 
(#67) seemed to best describe my problem when I went through the list.  I 
really need to backup my messages before I try uninstalling the gmail program 
which is no longer working. No downloaded messages for 5 days, and no response 
when I try to open any existing messages. Please help. Alternate email:  
jonandsid@yahoo.com  thanks
