Fatal Error: Uncaught exception 'Google_ServiceException'

I started using Google Analiticator ver.6.3.4 today… I did everything as the developers said to do and I got the Dashboard Analytics successfully. The problem appears when I try to use the Sidebar Widget. I’m getting this error all the time although I have done many times of Deactivating and Resetting the plugin:

Fatal error: Uncaught exception ‘Google_ServiceException’ with message ‘Error calling GET https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A&start-date=2012-10-25&end-date=2012-10-25&metrics=ga%3Avisitors: (400) Invalid value ‘ga:’.

Please if anyone solved this problem, can tell me what to do, because this is my reason of using this WP plugin. Thanks.
