Can't get to Fiddlers Green on my PC

Not sure where to post this problem, but:

I can't get to Fiddlers Green through Firefox or MS internet explorer, BUT, I can get through on my android tablet.



I've tried following Firefox's help to clear cookies etc, but still can't get trhough. I've seen other posts, not sure where, that other folks have had the same problem.



So can anyone HELP!
