I can load the files without problem, but near the loading end, the job desappear and nothing happen...

I start to be feed up, this is the 4rd time I load those files, and with only 1 project / day, this very long and painfully to try to participate to your project. (With SETI no problem...)

Sounds like you've hit the same BOINC download problem that many others have had recently. See <a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/forum_thread.php?id=2920#14677">this post</a> for the advised method of dealing with it.
