Can't log into the Auto Discovery

Can't log into the Auto Discovery

I installed the companion on both my Mac (10.6) and PC (Windows 7 Ultimate). While it appears that the Mac seems to be working ok, I am unable to log into the Google on the PC in the Auto Discovery screen. When I click on "Login", I get this error.

Login failed due to invalid credentials. Please verify your username and password.

I have logged into Google several times and have verified that these are the correct ones. Can anyone help me with this?
