Netflow not picking up interface

Netflow not picking up interface


Hello,
 
I have recently moved a circuit from one interface to another on a Cisco 7200 router, previously the interface has been monitored but due to this move I have removed the license.
 
After configuring the new interface on the router to send information to the netflow analyser the interface does not appear at all. I can not therefore manage/monitor his interface
 
Am i doing something wrong? Any ideas?
