ToB Final Battle Crash. Need Help with Mods [Tobex acting up?]

I am having a crash during the final battle of ToB, and I'm posting here because I know there are a ton of super knowledgeable mod people here. Basically, I just have SCSII and Ascension installed along with some other minor mods. I haven't had any crashes like this at any other point in the game, but the game keeps crashing in the later phase of the fight, after Amelyssan joins the battle alongside the remaining Five. After I crash to desktop, the TobEx window shows this error repeated dozens of times:

[Sat 25 May 2013 22:54:39] DETOUR_CEffectProficiencyMod::DETOUR_ApplyEffect(): Invalid wParam2Low

The TobEx.log is flooded with these messages, sometimes with a dozen happening in a second at which I assume is when the game crashes.

I looked up "wParam2Low" in the TobEx.ini and here is what is in there:
-----870 No Spell Interruption On Zero Damage [T]
Modifies the damage opcode such that if damage is reduced to zero (with normal damage behaviour; wParam2Low = 0), spellcasting and casting animations are not interrupted

Options:
-0: disabled
-1: enabled

I have never manually configured TobEx before, but can I disable this hack in the TobExTweak.ini somehow?

If someone can help me I will be so grateful, I have never beat the final ascension battle before and I am getting so close here!
