several times. by the way i'm new so is rtb pref on this website or on the blockland program?
To get to the RTB Preferences, go to the admin menu, hit Server Settings and hit Preferences.
don't unzip the files
place them in documents/bl/add-ons
Yeah, don't do that. Keep them zipped.
are you selecting Custom as your gamemode and selecting the add-ons you want to load?
Yeah, make sure that you're choosing the custom game mode. From there you have to choose JVS_<NAME>.
Please post a console.log as well if none of this helped.
Your console.log will be found in
Libraries\Documents\Blockland (Windows) or
/Users/yourusername/My Documents/Blockland (Macintosh).
