Hi Pierre,I have just tested the downloads and for me they didn't time out and downloaded at a steady 200kbs. Are you still unable to download?
Have you been able to download from other sites without problems? It could be a temporary issue with your ISP that is affecting downloads.
If you continue to have problems you could try downloading using a Download Manager which would stop you having to restart each time, and even if you do time out you could continue from where you left off.
You can find a list of Download Managers from the link below:
