Can't use new version of netflow!

Can't use new version of netflow!

There Cisco 2901 in our office.
Netflow build version 8100 was working ok.
Then i reinstalled it to new, 9100  - and it just say that there is no flow export to him...What could this be?

I already reviewed all configurations (firewall, router cfg) - and still cant understad why it doesnt works.
