Buldozer cannot load .paa file

[Certamine 10]

Okay so I'm making a CCO scope, I have done the model, and I have used a texture from an existing CCO from ArmA 2. I have been able to UV map the model and texture together, the model shows up in the main window with the texture on it, but when I open Buldozer I get an error saying "Cant load CCO.paa (CCO is the name of the texture file) and it just shows the model with no texture, even though it shows up on the four screens on Oxygen 2. When Buldozer loads up it comes up with a cmd window and shows this - http://i.imgur.com/75OaGlt.png?1

I would love some help ASAP I will be very grateful :)
