Well went to a starbucks, got the same error "cant download windows support software because of network problems"
Guess its an issue on apple's side.
Im able to create the bootable usb drive now with the new iso file i downloaded. No more errors stating it couldnt copy the files to the usb drive.
I will try later in the week. I know apple's network always has issues, i always run into issues with itunes match, and then i wait a few days and it starts working again.
I'm guessing it has something to do with the release of os6 coming up soon, i'm sure everyone in the world will be trying to download that and I think it becomes available tomorrow if I am not mistaken.
So kind of stuck for now.
