Blender main menu, Window - Toggle System Console

hey thanks :)
but...
Already tried that, it only shows the same message

When I try to export any model to source 2 blender shows that the export was successful but completed with 1 warning..

" 1 files exported in 0.5 seconds with 0 Errors and 1 Warnings "
how can i make blender or source tools to display the details of the warning ?
