Netflow configuration

Hi all

     hope this post finds everyone well.

     I am hoping that someone can perhaps assist me in terms of Netflow analyzer configuration as I seem to be having a bit of bad luck on this.

     We have configured our Cisco ASA for Netflow and set it to send traffic to the specified ip address we have chosen.

     I have also setup a machine with the specified IP and have installed Netflow Analyzer onto it and I am able to log into the web front end.

      I have verified on the Cisco Asa that the information is being sent to the specified IP, however when I log into the Netflow analyzer it just shows no data.

     I am however suspecting that I need to configure something here, however I am unable to find any documentation , etc... to point me in the direction of what I need to configure or how to get the data into Netflow Analyzer.

    Can someone please assist as any help will be appreciated.

Regards
