So I'm downloading the new server software after a long time to host a private server.
However, the .rar only contains 3 files, README.TXT, minecraft-server.jar and start server.bat. It's missing alot of files, like server.properties and admin.txt which I clearly remember using before. Starting the server .bat gives me an error aswell.
Edit: I fixed it, I simply forgot to take the files out of the .rar file which is probably why I couldn't auto-generate the files. My bad. Thanks for the help everyone!
