No, nothing works...anyway I added an official repository containing the 5 suse 9.3 iso's and it seems to work.
the PRO is that I won't have to change cd's at everytime I have to install a software
the CON is that is much more slower...
...I'm going to say I'm happy with this solution, or at least half hapy
Anyway thanks so much, you have been so kind with me !
