How do I unlock my google account?

I am trying to use blogger to blog with MS Word2007.
When I register my username, I get an error saying "Word is unable to
complete this action because your Google account is locked. To unlock your
account, please click the More Information button below."
When I click the More information button, Word opens Internet Explorer with and this URL is invalid. Now, I have no idea what to do.
Any thoughts?
