Is Resorces.Load() unavaiable on Windows Store?

I’m trying to load at runtime textures with Resources.Load (I need to load them in this way, they are hundred of little textures and I cant assign all to the script). The textures are in the Resource folder obviously, and the script load them in the editor when I play the scene. When I export for Windows Store the app can’t load them, and the objects are pink. I’s a problem of Resources.Load()?

Your Objects are pink ? That sound more like a missing / a not compatible shader. If a texture is missing its usual another color depending on the shader.
Any luck with the log file on the Windows Store app? If any resources could not be loaded you should be able to find it out in the log.
