error when launching render from sketchup

[nacmon]

hello,

when i start my rendering from sketchup,
it opens indigo and i can see the preview but i have an error message that gives this adress.
If i try with the default scene there is no problem.
Is it becaus my model is too heavy?
or my computer not powerfull enough?

A problem occurred with the scene:
Error while building scene: Error while loading diffuse material 'feuille 2a': Failed to load texture 'C:\Documents and Settings\simon\Application Data\Indigo Renderer\TX_default/feuille_2a.png': LibPNG error: [B0][B2][BA][F2]: invalid chunk type.
Indigo version: Indigo Renderer v3.4.16, Windows 32-bit build.
Exporter: SkIndigo version:3.4.12
Platform: i386-mswin32

You should read that error report, it tells you exactly what is wrong!

The problem is that SketchUp saves malformed PNGs. Indigo tries to be permissive, but sometimes the PNGs are too screwed up to load.
