Please provide any additional information below.
Addon works for all other toons except any newly created toons. For the purpose of trying to trouble shoot I had removed all addons except SB and removed the wft folder and let blizz recreate the folder.

Update, I have found the issue, but still unsure why it does it. It appears that it has the error until I have gotten high enough and bought atleast 1 skill in each of the class's spec. ie: as Paladin: 1 Holy, 1 Prot & 1 Ret.

SpellBinder.lua
Line : 395

	function SpellBinder:BuildTable()
		currentitem = nil
		options.args = {
			school1 = buildschool(1),
			school2 = buildschool(2),
			school3 = buildschool(3),
			school4 = buildschool(4),
			item = builditem(),
			macro = buildmacro(),
		}
		--[[if HasPetSpells() then
			options.args.pet = buildpet()
		end]]
	end

The issue is because the author is assuming you have all four tabs in your spellbook. Not sure how to correct it, but maybe some type of checking to see if objects exists before trying to access their properties might fix this problem.

Fix committed. Download r6 from files section or Curse Updater
