[Gvsig_english] error raster layer

[Claudio]

Dear all,
I'm testing gvSIG OADE 2010 on my macos intel with leopard and jre1.6.  
It's work fine, but when I try to add a raster layer (es. dem.tif that  
I had elaborate with another gvSIG version 1.9), gvSIG returns me an  
error message.
If I try to create a new raster layer, I have the some problem and no  
one raster layer is created.

What is the problem?

Thanks
Claudio
