Odd Error "Stream Read Error"

[Atrocities]

I am getting this error when I select Starship Tactical Center I in AST mod 2.1. I have checked the image files and they are both present, the 128x128 image and the corrosponding 36x36 image are both present and correctly numbered.

I checked the data files and could not see an error.
