Proxy problem

Proxy problem

Hi,
I have a problem with my NFA Distributed edition 11 Build 11000. On both collector and server I have the notification "New update..... Please configure proxy."
The proxy is configured with good credentials (tested with IE), I tested without proxy and the message is always here.
Why?
2nd question : I wouldlike to upgrade from build 11000 to build 11001, is-it possible to do this from application?(I looked at the documentation with stop / start service and the updatemanager) Because I didn't find the patch file on the website.
Regards,
