Bump effect problem

[manelet]

Hello,

I use Sketchup 2015 and Vray 2.0
I am having problems with Bump effect with Normal Maps.
I downloaded this texture with the maps and I am getting this weird results. I am using the Normal map texture on the Bump slot and Bump type: "Normal Map (tangent Space)

The light is hitting both faces(90° faces) with the same angle and intensity, but it looks like on the left side, the shadows are upside down, as if the light was coming from down.

any ideas of what I am doing wrong?
thank you
