NetFlow Analyzer shows only last 24-hr data

NetFlow Analyzer shows only last 24-hr data

I just installed NetFlow Analyzer Free Edition a few days ago.  I notice that the charts show the data ONLY for last 24-hrs, even if I select longer time period, like last 7-days, 30-days or Custom.  I am on build 12200 and was told to apply the latest fixes and I did.  Issue still remains that I cannot see data older than 24-hours.  Any help will be appreciated.
