Need Help Creating an "Install" Splash for my UI

[Cerberux19]

Hey all, I was looking to make my UI a bit more user friendly and create a separate addon that will simply load a splash screen the first time a character logs in and needs to set up my UI.

Currently I am using a string that incorporates the addon "Reflux" to load all addons in a single profile.

I have been trying, with no luck, in creating my own addon. And I am at a total loss atm.

The folder so far consists of the following files:

CerberuxUI > Core > Settings.lua
Media > Install > INSTALL.tga and Logo.tga
CerberuxUI.toc
Core.lua



These are the codes I currently have in each file:
Could someone please take a look and see where I might have gone wrong?

Settings.lua

	initialized = false,
	needchatmoved = true,
}

local IWTextures = {
	Logo = [[Interface\AddOns\CerberuxUI\Media\Install\Logo.tga]],
}

local IWF = {}

---- Misc functions
CerberuxUI.deepCopyHash = function(t)
	local nt = {}
	for k, v in pairs(t) do
		if type(v) == "table" then
			nt[k] = CerberuxUI.deepCopyHash(v)
		else
			nt[k] = v
		end
	end
	return nt
end

p.s. I am very new to LUA and creating addons and recycled this code from a similar style splash so please pardon the ignorance.
