Wamp Server Problem for KZ Arg Top15.

Hi , i have a problem with Wamp Server 2.0h. I open it and when i type /top15 in chat i'm the only who can see the top15... No one except me can see the top.
Also no one can enter the webserver i create. http://89.36.53.118 ,except me.
Some people told me it's because of firewall , but the firewall is turned off.

I'm talking about Kz-arg 2.0 beta (sql).

Anyone can tell me how can i solve this.
