I am having this issue as well. I have had the software for a few months now. This error only occurred once the program was released as free software. I tried uninstalling it as I thought that may be the issue but have come to find out that was a bad idea as now I can not even log in to re download my software that I need for my project. I personally do not wish to uninstall bitdefender (which i do use) as that would not be a valid idea considering I rather not leave my PC un protected.
