New Act7 'Index was outside the bounds of the array.'

Hello, I'm parsing the new Act7 files, but everytime i'm getting 'Index was outside the bounds of the array.' on the factory.ImportNpcMonsters();. What could i do?
Before i had mostly issues on the npc."ELEMENT"Resistences, so i disabled those from parse and i got other array issues until I didn't displayed on the whole Function.

Any idea on how to fix?

Need chnage to short

Opennos.Data -> NpcMonsterDTO:

CHANGE :

public sbyte DarkResistance { get; set; }

public sbyte FireResistance { get; set; }

public sbyte LightResistance { get; set; }

public sbyte WaterResistance { get; set; }

BY:

public short DarkResistance { get; set; }

public short FireResistance { get; set; }

public short LightResistance { get; set; }

public short WaterResistance { get; set; }

and after ImportFactory:

CHANGE
npc.FireResistance = Convert.ToSByte(currentLine[4]);
npc.WaterResistance = Convert.ToSByte(currentLine[5]);
npc.LightResistance = Convert.ToSByte(currentLine[6]);
npc.DarkResistance = Convert.ToSByte(currentLine[7]);

BY

npc.FireResistance = Convert.ToInt16(currentLine[4]);
npc.WaterResistance = Convert.ToInt16(currentLine[5]);
npc.LightResistance = Convert.ToInt16(currentLine[6]);
npc.DarkResistance = Convert.ToInt16(currentLine[7]);
