Yesterday we identified a bug in the AdWords API registration process that is preventing some developers from successfully entering their billing information and accepting/rejecting the Terms and Conditions. We have identified the issue and hope to have a fix in place in the next few days.
Please note that this bug only affects the “billing information” stage of the registration process. Therefore, all users are still able to complete the “developer and application information” stage of the process.
In the meantime, if you need to review the new Terms and Conditions, you can find a temporary copy available at http://www.google.com/apis/adwords/terms_preview.html.
We apologize for any inconvenience that this may cause you, and we will notify you as soon as this bug is fixed.
