Okay, onactivate is admin only because of Event_Owner doing this:
registerInputEvent("fxDTSBrick","onActivate","Self fxDTSBrick" TAB "Player Player" TAB "Client GameConnection" TAB "MiniGame MiniGame" TAB "Owner(Player) Player" TAB "Owner(Client) GameConnection",1);
Notice the 1 at the end which should be a 0 or left out.
