I just bought 2 days ago the DB BR 182 and its only installing but i cant play, iam getting mad now, can someone help me?
Have you tried deactivating your PS4 as Primary and then reactivating it? You can do that by going to Settings > Account management > Activate PS4 as primary. It's a Sony issue and i've had to do that for my downloads to work.
Not a very helpful comment! To the OP, a couple of people have had this issue and it is all down to their Sony/PSN accounts and being set incorrectly to non-primary. This invalidates the licence. I have not had the issue, but someone above has, and their description will hopefully solve your issue.
I had the same problem, the BR128 wasn't showing up in the Scenarios and Services in Fast Track but I didn't realise that it WAS in the Tutorials and they have to be done first.
