There is indeed a Let's Go button in your screen shot. You must use it, nothing else will help, you cannot submit until your ID is accepted. So, exactly what happens when you click Let's go?
Why can't you access the Let's go button? What happens?

I believe this message has to do with the set up of your Contributor Account. Click the "Contact Us" link at the bottom of the page and describe the problem if you can't figure out how to submit your ID.
