I have seen many posts on this, when I go to the library and click on the countdown there are two times that should be considered.
1. Expected Auto-Download Date: 09/05/2014
2. Time until release: (countdown) 3 days 14hours 51 minutes...
Keyword here is release, not download. Many know that once you download and come 9/9 that you cannot play until PS verifies certs. This is the release date, that is when PS will release your game respective to your countdown.
So, recap, your countdown is when you can play, download would have already occurred.
Edit: inaccuracy

You may want to double check your countdown. What system?
