Then you can't use it until they update.Just remember,making mods can take time and this is no exception.my terrariaoriginalbackup.exe still uses the steam folder so it doesnt work cause it says its 1.2.4.1 but since the folder uses 1.3 it isnt compatible or so i think so i just deleted my terrariaoriginalbackup.exe
