I reply myself...
It's a color problem (I don't know what kind of problem).
Just open an max file that works fine. Go to post process, preview the layer that generate problems in your file. With preview the layer press right button and "save color setup".
Then open your wrong file, go to post process, preview the layer that generate problems (it doesn't generate the preview, it doesn't matter), press right button and "load color setup", then load your previous color setup backup.
Then, make preview another time to wrong layer and now it must be corrected...
