Hi Ken, This error is likely do to a Google Apps domain migration on the account you used in the clientEmails field:
http://adwords.google.com/support/aw/bin/answer.py?hl=en&answer=188607 Have the user log into their account, complete the migration, and then log into the AdWords web interface. This will update their account information and the API should work again.
