I got the message too and sent playstation a tweet but they referred me to askplaystation so I think they might have thought the issue was an internet connectivity issue maybe or misconfiguration of my network settings. I knew it wasn't just me though I'll just try tomorrow.
I was really nervous and thought it was just me. I was so looking forward to this game, and I have to wait even longer. I have a few friends who were able to download the game, or at least the said they could.
