My server was registered here not by me or my clan and i want to delete it. I think that I will have to claim it first in order to delete it. Tried to do that but says you need to change name to gametracker. I am unable to do this as a Multiplay server which forces a prefix Multiplay::. So renamed server gametracker is overwritten to show Multiplay::racker.

Very annoying I did not want my server on this site and now i am unable to delete it. Can someone please tell me how to resolve.

As the claim dialog help says, it would need to be "Mulitplay.co.uk :: GameTracker" in this case, not "Multiplay::racker".

Ok done that still doesn't work as below:

In order to claim ownership of your server you must temporarily rename it to:
GameTracker
This server is currently named:
Multiplay :: GameTracker

Please check your game server config file, restart the server, and try again.

Moved to bug reports.

You should now be able to claim ownership of the server with the server name in the format "Multiplay :: GameTracker".

How to check the game server config file, restart the server?
can anybody plz tell me the process in detail.
