Thanks for the responses, most helpful and responsive forum I've used in a long time!
Just to be clear about what is happening for me.
If I follow the Galaxy at War link without being logged in I get "The profile you are trying to view is not currently available." error.
I then log in, view my profile which is fine. I click the Link for Galaxy at War again and the page just hangs and depending on the browser I get a message stating the site has tried to re-direct me too many times. In Internet Explorer the site just continues to load without actually working.
I've tried the solution ChronosTachyon suggested, but the page still doesn't resolve.
It seems strange to me that I can view my characters, progression and unlocks, but not the Galaxy At War page.
