missing POP accounts in main page

missing POP accounts in main page

I made password changes to my POP accounts and updated the password at the domain level as well.  When I go to my main mail page, none of my POP accounts appear.  In addition, when I go to Settings--> Mail Accounts-->  the screen appears showing the accounts but is in a constant LOADING...  state.

Any suggestions as to how to get my accounts to reappear in the main page and be able to adjust settings as necessary?

Thanks
