Unable to extract raster values by Extraction / sample

Dear all,

I want to extract values from multiple (~10) rasters using the "sample" command of Spatial analyst, with a set of ~20000 points.
I did so last week, and I get a tables with the coordinates and the values i seek, it worked perfectly.

All of the raster are integers and have a attribute table. I obtain the values I want using "extract values to point", but using the "sample" command (that allow multiple sampling) yield a table with the right fields, but empty cells (the coordinates are ok, but that's it).

I am puzzling because I have the feeling that I did the same (?) last week and it fails now. I am stuck since five days on this. Any halp highly welcome :-)!
