Below are steps required for new google accounts before adding/using them in GBloggerBuilder for the first time.
================================================== ===================

1) In your web browser log into with the user details of the new account.

2) In a new tab in the browser log into for the account.

Enter a Blogger profile name for the account then click Continue to Blogger

On the next page click the link Revert to legacy Blogger

You'll then see this screen and the account is now ready to use in GBloggerBuilder

When you run GBloggerBuilder using the new account in most cases you'll see a Security email in gmail so switch back to the gmail tab in your browser and click on the Security email to open it,

On the next screen click Check activity

Then click Yes, it was me

After those steps your GBlogger project will run smoothly with the new account.
