I have a banner of server on my page http://www.gametracker.com/server_info/89.176.38.105:25565/
And if I cliked on it it writes "THE SERVER YOU REQUESTED IS NOT IN THE GAMETRACKER DATABASE.". I think ok i readd it to database but it writes "A server with this ip/query_port already exists in the GameTracker database.". Before thanks and sory for my English I'm from Czech Republic.

I am assuming you are entering 25566 as the query port. You will not be able to use the same IP and Query Port for two different pages.

Please visit http://www.gametracker.com/server_info/server.php?GSID=2857953 and delete that server if you would like to add it using a different join port.
