Reconnect to GMail without losing folders

For reasons unknown, I had a few days of very intermittent internet access; I think that is what triggered Google to autolog me out of my account. I managed to log back in again, but it seems EmClient got disconnected from Gmail. The advice on the web, is to use an ‘automatic email wizard’ to remove, then re-add my Gmail account. I do not know how to access the Wizard. I saw a ‘remove’ option, but it warned me that all my local folders will be lost if I proceed. I do not want to suffer that loss, but I need to reconnect to Gmail. What is the way out of my predicament ?

It came good by itself in a couple of days.
