I just bought a server about 2 hours ago and accidentally chose the option to put it on the Experimental version of Rust. Now, for some reason, in my.gameservers.com, i the option for changing between the two is gone and i have no idea how to put my server back on Legacy. I cannot load Experimental very well but when i go to Gametracker.com i can see that my server is running on Experimental and is up. I just need someone to help me change it back to Legacy so i can play and manage it.

Have you tried contacting GameServers support? They would typically be the ones to provide support for their own control panel...
