Ok, I am not the Gmail guru, and I regularly see posts of problems in setting up Gmail accounts. My suggestion is to remove the account completely and start over. And this time, do not enter password during the setup process, but wait until the Google screen pops up and asks for it. No guarantee, but it usually works for me.
