NIS 2011 & eBay

I have recently installed Norton Internet Security 2011. It is performing fine.

 

I find that I am unable to load/open eBay. Is there a setting in NIS 2011 that needs adjusting to allow eBay to open?

 

At the moment, when I try to open eBay, the connection "Times Out"

 

I am using Firefox as my Default Browser.
