Netflow device accidentally deleted

Netflow device accidentally deleted

As I was getting familiar with the creation and management of the Netflow add-on, I deleted a particular device. It was gone, and I was comfortable with that. Although.. Now that I know what i'm supposed to be doing (!!) I need that device to come back. :| 
I have tried suggestions of stopping netflow from the device and adding it back on, I have also changed the source port on the device, so it would report it as another device. To my attempts, I have no success story to brag about!! It's still not coming back.

Question: Since I deleted it in OpManager, is OpManager now ignoring the Netflow posts from this device? I read that as long as the device was sending it, it would re-appear on the screen. In my instance, it is not happening that way!!

Thoughts?
