Cant download add-ons

Hi Guys,

can ping mirrors.xbmc.org
dns is set to 8.8.8.8 (removed unblock-us dns as possible cause)
weather in xbmc works fine, RSS feeds look to come through
I have cleared all filters etc off by router/gateway.
system network info show internet as "busy"


yet when i attempt to get/download an add-on it sits at 0% and does not progress? tried this with a number of different add-ons (eg Hulu bETA, TED Talks)

Ideas on what to look for would be appreciated.

Thanks - Matthew.
