g-mail user here, on Win 10 (x64) with ESET Internet Security installed.
I am getting the dreaded red circle (i.e., cannot connect error) when I update from V7 to the latest version of V8.
I can send e-mails, but cannot receive them. (The red circle is present all the time.)
Other than reinstalling V7, which works perfectly BTW, does anyone have any advice on how to troubleshoot the V8 installation?
