T's Combat Stats Error

[drasn]

In referance to the addon: T's Combat Stats:
I'm getting the following error whenever I receive XP towards a skill line that is not maxed:

user:/Addons/TsCombatStats.lua:1734: attempt to index a nil value
stack traceback:
user:/Addons/TsCombatStats.lua:1734: in function 'TCS:OnEventSkillXPUpdate'
user:/Addons/TsCombatStats.lua:1201: in function '(anonymous)'


To clarify, XP towards individual skills does not trigger the error. It is only triggered when a skill line that is not maxed receives XP.

Examples:
Picking up a lorebook while lower than mage guild 10.
Killing a daedra while lower than fighter guild 10.
Receiving any XP(killing, questing, exploring) with a bow skill slotted while bow is lower than 50.

Does anyone know of a fix for this? I have Garkin's Update 5 fix installed and the error persists.

Short of a fix is there another Add-on with similar functionality available?

Thanks in advance.
