if i recall it correctly, all of you guys are using transparent mode right? I think i found the issue, the domain status.fw-notify.net is currently not resolvable. This is the issue of your problem. Therefore the download manager only works in Standard mode, and not in transparent.
I will take care of that.
As a workaround you can add an entry in the hosts file of your client machine: C:\windows\systems32\drivers\etc\hosts
