Thank you for your help..

Fred.

Check permissions for language/en-GB and administrator/modules directories of your site.

Thank you for your answer but all my folders are on 777 !
and i'm the owner of the files..

I don't how to assist here. The only ideas that I have are that you either
1) login to backup/reserve server (it may be in the case of your hoster moves website to another servers and as a result you login to old server while the site is onnew server),
or 2) you exceed disk quotas.

I send you my different access  by private message if you can't maybe have a look, 
I tried many many time and remove it again. So Mobile is not installed yet.
That would be very nice if cant do this because the site is not realy active before next week.
I make a backup and let's go again.

Thank you for your support.

To me it says "Installation d'un composant : La fonction DB ne rapporte aucune erreur". So,
1. Try to apply this patch: remository.com/downloads/support-files/joomla-1.5/database-interfaces/
2. AdminPanel says "Your hosting is permanently limited to 64 MB memory and 10 seconds for execution". But MJ takes ~30-50 seconds to be installed. This time may be decreased by unpacking MJ archive into joomla's tmp directory and use "Install from directory" method. And even in this case 10 sec seems insufficient. But you have an options "Temporary deblocking for 5 minutes and 128MB during the next hour" in AdminPanel, I didn't try to enable it (because of it's limited to 10 times per year and maybe you keep it for further usage).
