Okay, so I need help how to delete old gamemode, so I could start uploading my new resources. In my old GM that I got from internet was a big mess (even the log in didn't work at all)... So I deleted all resources, restarted server from host, but still. Get that old gamemode on my screen whenever I try to enter to server. Now I started fresh today. Created few resources, uploaded them but I still get my old gamemode pops out when I go to my server. How to delete it entirely?
