Saiku Analytics CE (3.8.8-PENTAHO) from Marketplace can't see cubes from a schema

Hi. I'm having problems using some cubes with Saiku Analytics CE on the PUC v6 CE.
I installed the only available CE version of Saiku Analytics on the PUC Marketplace : "3.8.8-PENTAHO (CE)".
The cubes published in a schema (FoodMart) just don't appear.
Any idea how to make this work? Thanks.
