No Router is currently exporting NetFlow packets

My sniffer shows UDP 9996 packets making it to the NF5 server, however I still get this error:

No Router is currently exporting NetFlow packets to NetFlow Analyzer.

I've been refreshing this screen for 2 hours. I vaguely remember having to configure a group to get this working the first time... that may have been another netflow product.

I had this working a few weeks ago, uninstalled NF5, then after reinstalling NF5 today now it will not recognize the netflow packets.

Router#sh ip flow exp
