Please do not use Sourceforge. We host client files on https://download.ryzom.com now to prevent some troubles.
The problem also might be that you are using older version of the installer that is configured to download files from Sourceforge. We have no way how to update its configuration to use new URL. In such case you should download new installer version from ryzom.com.
