HOW TO REAUTHORIZE FOR GMAIL

[cc green]

I CHANGED MY GMAIL PASSWORD. ALL OTHER EXTENSIONS FOR GMAIL ASKED ME TO "REAUTHORIZE"/ALLOW. I DID NOT RECEIVE THIS FOR MAIL CONDUCTOR, BUT GOT ERROR MESSAGE VIA EMAIL IN GMAIL: 

Summary of failures for Google Apps Script: Mail Conductor; "Authorization is required to perform that action." I cannot find a way to "authorize," so anyone who can help would be greatly appreciated. Thank you
