I've updated the API to comply with the latest changes by Google. However, since the change required some code changes, in addition to the changes to the regular expressions, we will have to wait until the guys at CodeProject upload the new version to the site. I've sent them an email with a request to do it asap - usually it takes a few days. Hopefully this time it will be a little bit faster.
Update: I checked the article - it is now up-to-date. Please let me know if there are any more problems.
