Thunderbird has stopped working

Question

Hello,
Starting on 04/08/2014 the Thunderbird has stopped working in any way in my PC. I am running Windows 8.1 Pro x64. Before that day everything was ok and Thunderbird was working. I asked some friends using Windows 8 and they have the same problem. Thunderbird won't load the email accounts and won't send and receive any email. It won't even let us add a new email account. The message received when trying to add a new account is the following "Sorry - we're unable to communicate with our sign-up server. Please check your connection.". Also if we will try to move forward and add a new email account anyway the answer will be that Thunderbird can't connect to any server. We have uninstalled Thunderbird and install it again several times in the past days with no success. I was looking t delete the Thunderbird folder in Program files but I can't find it. The uninstall and install again procedure including deleting folder was a solution few years ago but it seams that now is not working anymore.
In the past 2 weeks Thunderbird started working only for few hours and we have the same problem again. I was asking around 10 people working with Thunderbird and they have the same problem at the moment and they had the same problem in the past month.
Of course I turned off windows firewall and test if Thunderbird will work but it was not a solution. I am running windows 8.1 Pro x64. Thunderbird is not on the list of the allowed or not allowed software through firewall and I can't find any option to add the Thunderbird to the list in order to try to solve the problem.
I am running BitDefender antivirus and I turned off the BitDefender firewall and the same thing happens. I also turned off the whole antivirus functions after and the same thing. I turned of bot windows firewall and BitDefender firewall or turned off the whole BitDefender and the same thing happens. I checked the BitDefender firewall and the Thunderbird has full access.
Also I have checked the Windows updates. I usually not allow updates in my PC. I remember that I choose not to install Microsoft updates ever. I checked the status and it is set up not to install Microsoft updates. I also checked the "update history" and is empty an the status is "you have not tried to install any updates on your computer".
I started windows 8.1 Pro x64 in Safe mode with networking and started Thunderbird while windows was in safe mode and it has the same problem.
I am trying to add Gmail and AOL accounts in Thunderbird. The emails are all set correctly and working well in browser or other email client.
Today (04/21/2014) Thunderbird has the same problem.
Any help will be much appreciated.
Regards
