NetFlow Analyzer 12, "No Data"

NetFlow Analyzer 12, "No Data"

Downloaded the free version.  Getting "No Data".

Used Wireshark to confirm that netflow packets are being received on the correct port: 9996.

Used SysInternals TCPView to confirm that java.exe is listening on that port.

Netflow (version 9) packets are being from a Ubiquiti EdgeRouter X.

Is there a next step I can take to debug the problem?  Is there, for example, a way to see if the NetFlow data is being accepted by the java code?  I've had issues with other Netflow ingestors failing to parse the EdgeRouter's periodic Netflow template packets.

thanks,
