How do I unlock my google account?



Hi
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
http://r.office.microsoft.com/r/rlidBloggerCaptcha?clid=1033&ver=12&app=winword.exe and this URL is invalid. Now, I have no idea what to do.
Any thoughts?
.
