Rest on loading [RESOLVED]

Hi

I'm French and my english it's not very well.
Sorry
My app Download center rest on loading.
My windows app Download Assistant has the same problem.
It's write "Timeout connection".

However, all others apps are OK.
Every services/users/connexion/boxee/web are OK.
Eventviewer is OK.
I have restart my nas, but without success.
I can't uninstall Download center because of download en settings.
Please, can u help me ?
Thx.
