Admin keypad checker problem

I have the admin keypad checker on my Darkrp server but everytime I click on it and equip it, I get kicked for to many lua errors.

[LUA]
[ERROR] lua/includes/modules/draw.lua:243: ‘UiBold’ isn’t a valid font

  1. SetFont - [C]:-1
  2. WordBox - lua/includes/modules/draw.lua:243
    3. unknown - …darkrp/entities/weapons/weapon_keypadchecker/cl_init.lua:13
    [/LUA]

I know about sv_kickerrornum 0. I was wondering if there is a fix for this problem I am having.

Well looks like it uses a font from gmod12? try some font from here wiki.garrysmod.com/page/Talk:Libraries/surface/SetFont
