I got also the same problem, the community updater doesn't launch, and when I try to open it, it starts the upload but it seeds nothing, and finally a window comes and say : "BackupLinkWindow : Could not reach any of the servers, if an emergency link has been provided, please enter it here :"
I heard someone said that it is because the download version is too old. Are the Community Updater links outdated ?
Thanks for reading me,
