I see this same problem. Using WinXP, outlook 2003, just downloaded
KiGoo tonight and it gives a "KiGoo Login" box, "Error connecting to
the server" after entering my username and password and pressing the
"Sign In" button. This is a new google account I created tonight that
is failing. When I try to connect to my other gmail account that I
created over a year ago, it signs in just fine. Seems the issue has
something to do with the gmail account end, although I have failed to
find any settings in gmail that allow KiGoo to get in. I also tried
another sync application with this new gmail account that failed as
well.
