Ok so the issue is, I run the server file, and it says CSS is not loaded, and to try playing it first. I have no idea how to play it (I have css in my steam on same machine, if that helps). I really want CSS to work and I have tried deleting the css part and using the server updater and re installing. Any ideas?
