Solved by me
Go to this directory.

D:\Profiles\<username>\Local Settings\Application Data\Google\Google Talk Plugin

Delete the googletalkplugin_port file if one exists. My system did not have one.

Double-click the googletalkplugin.exe file.

It will recreate the googletalkplugin_port file in this directory.

Go to your Gmail account and test the voice and chat plugin. It should work now.

Thanks for this fix eklisiewicz! I burned many hours trying lots of suggestions that DIDN'T work.
