Live Server Not Available

It seems that deleting the chess.com cookies does the trick.
In FireFox that's easy;
Tools->Options->Privacy->Remove Individual Cookies->Select "Chess.Com"-> Remove Cookies
For IE, I have no idea how to the same thing.
I got all last day the same: "Live Chess server is currently unavailable..." but before I saw: "There are currently 2107 players online!" How comes?
I've been getting this message for the last two days. I'm using IE so I switched to FireFox and I don't get that message. Is there something about IE, maybe a setting that I need to change?
I have to use IE because there are other sites I visit that don't work in FireFox but are ok with IE.
