Folks, ARKON does not work for ATLAS. It may work for ARK and I have used it quite a bit for ARK. For ATLAS however ARKON quit working many patches ago and the developer does not seem to be interested in repairing it claiming it is an ARK problem.
I have verified this through a support ticket. I would think removing the link on the Atlas server page might be a good thing so that people don't go through unneeded frustration.
