ok is there any way to clear this oath of this wall?

Well, you could delete the clission, but that won't help I don't think.
Pretty sure that "wall" is part of the model itself.

ok so i have to go into XSI and open up that area of the wall?

... yea, if you have xsi full version, and the full version of 3D object converter.
Total cost: Aproxx 1500$ + 50$
Exporting your own goodies: Priceless.

lol ya can't afford that

Someone else could do it for you, but I don't know anyone with the full 3D Object Converter.
