Using Mozilla Thunderbird 45.2.0 on Windows 10. Has configured multiple a/c on it. Was working fine but since last two days not loading e-mails
I am using Mozilla Thunderbird 45.2.0 on Windows 10. I have configured multiple e-mail accounts on it. It was working fine till 2 days back. Now none of the e-mail are getting loaded. Even I leave system for 1/2 hours Thunderbird show still loading. I could see new e-mails on webmail. I did multiple time reboot of my system and also my DSL modem. Also not able to send any new e-mails. It seems to me Thunderbird is going to unknow sate and not able to recover.
When I close and restart Thunderbird in above said state, I get "Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window.". Please let me know how to recover from this state?
