[all variants] THUNDERBIRD-Sudden negative issues

Hello all. I've been running all current versions of webmail/yahoo webmail extensions and Thunderbird. I had been working fine all morning until I started getting the negative vibe error. I don't remember any new yahoo updates and of course I've more than verified my settings. I've tried to uninstall/reinstall...to no avail. I've tried different ports...I've logged onto my actual yahoo mail...(that had no problems)..I'm kind of stuck. Is anyone else having or recently had this issue and do you have a solution? Thanks so much in advance!!
