Error setting game configuration : This URL is already taken

I created a game, which had to be deleted, as i forgot to activate the game manager. after deleting the game and creating a new with the same name I cannot user the original URL, as the error message above.

How can i use the same URL?

Try disabling, then enabling game manager once again, that should reset the URLs

The URL remains reserved, so after disabling the game manager, change the URL of your single game, to make the name available, before re-enabling the game manager.
