I host a minigame server, and i have installed a couple of course maps, but when i go onto the course maps it says "Theres too many CT's!", and only one player can play

If you know the solution to this problem, please reply thanks.

Most of our customers do not design their own maps. You may find better luck in mod hosting forums, or custom map developer forums. As a company, we cannot provide assistance with map creation since we do not make our own maps.
