NIS 2010 - Firewall Rules..........blocked by accident

I have trawled the www for this but I am really struggling.

 

I accidentally (not sure how) have stopped Adobe Lightroom upload services for flickr from accessing the internet.

 

lightroom.exe is shown in rules as allowed, but I am unable to locate the process that enables me to upload images from

lightroom straight up to flickr.

 

The process is not evident in task manager.....and I am not experienced enough to do anymore....

 

Could some one point me in the right direction, either finding the process and unblocking it or resetting all my rules (which i dont really want to do)

 

Many Thanks in advnace.
