ALSO, if the reinstallation does not work properly for you I have found that this is another possible solution:

Logging out of Gmail

Going to C:\Documents and Settings\Administrator\Local Settings\Application Data\Google\Google Talk Plugin, or your OS equivalent

Delete the file 

"googletalkplugin_port"

Log back into Gmail, it should be working again.
