Ryzom

Hi,
I have a HP Pavillion Notebook with Intel Core i5 CPU, Intel Ironlake Mobile
With the previous version of Ubuntu Ryzom worked. Now it crashes. The terminal dispays this message:
Patching Ryzom data...
Launching Ryzom...
Segmentation fault (core dumped)

How can I get Ryzom working again?

Thank you very much,

Alberto
