Here is what I did. It is manual, but it works!
From my hosting company's Cpanel
Went into phpMyAdmin
Clicked on the wordpress database for my particular blog
Browse/Open/Look in database table wp_wp_email_capture_temp_members
You will find the unconfirmed emails there
The next step I did to confirm REAL email addresses
I copied all the confirm_code into notepad
Next, I copied each one to the END of the hyperlink that is sent out when the system ask people to confirm
At the end of that link you will see something like capture_passkey=somerandomstuffI replaced the somerandomstuff with each confirm_code
Paste the entire link into a browser and it will confirm that particular email.
You have to do one by one, slow but it works.
