that's what i did but its not showing up on the server list
Same.
Make sure your server is off. Replace every file that I recommend below this sentence, after that, you can turn the server back on.
drag your base folder into the blockland ftp, overwrite everything, also, replace the dlls. Don't replace your key.dat, but replace your
Blockland.exeIf you ever have replaced your key.dat (which might be why yours isn't showing on the server list), edit the config/server/musiclist.cs, at the bottom put
schedule(10000,0,setKey,"XXXXX-XXXX-XXXX-XXXX");
