Transformers: Fall of Cybertron

[#1]

So, I bought the PS4 port off PSN, and, when I did so, the download said it'd be around 11GB.

About 10 seconds later, the dowlnoad changed to around 5GB

And now when I'm in the main menu and try to access Multiplayer, Escalation, or Extras, I get a message saying; "Transformers: Fall of Cybertron has not finished installing. Please wait..." and a progress bar.

The progress bar starts at 90% and gets up to 91% but hasn't budged from there.

Anyone else get this problem? Anyone playing the multiplayer at the moment? Did I just waste $50?

Edit: Just as a side note, this is the first time i've had to use the Activision forums, and I log on with some strange community username? How'd I get this? I look like a ***** bot now.

Welp, I didn't notice that it starts another download in the background, so you can play the campaign whilst the rest of the game installs. Silly me; PAY NO ATTENTION TO THE IDIOT BEHIND THE CURTAIN!
