Couldn't load resource es_admin2. :(

I get a error with Couldn’t load resource es_admin2. When joining my Server.
I already made a reply on the page of the resource but I got no answer so far.
How do i fix it? I keep rejoining the server but that doesnt help and if people have to rejoin many times to download the resource it won’t be a very attractive server to join on…

Fix?
