Aster 11 Update and Sta10.1 in SalomeMeca2011.1

Hi all ,

Does anyone tried to update aster11 in caelinux2011.
I tried to do that and I failed. I launch the update and make it succesfully but then code-aster becomes useless. I cannot launch any analysis.

I check the referred modifications to make in aster website. But all of them have already been done. ( no need to modify config.txt for med3.0 because there is already med3.0 for example ).

How can I succesfully do that in caelinux 2011 step by step. I am a bit confused. ( also I cannot use salome meca 2011.1 with sta10.1 when I either install it in /opt or /home/salomemeca2011 (custom file name).. I launch it but new salomemeca starts and I cannot choose Sta10.1 from aster window..)
I'll appreciate any helps. Thanks.
Regards

Kamil
