ESPN Credentialed Player Database (PPD) corruption is a bug that allows the database to be corrupted by corrupted client software.
PPD is used by the PS4 to track players on the PlayStation Network.
This is not a problem with the PPD itself, but with the client software which the database connects to.
The problem is that the client is unable to access the database as it has not been updated for several months.
This has caused PPD to appear as if it is corrupted.
The game will show an error saying “This is not the PDP, this is the client”.
Once this is fixed, the database should show up as the default version.
If it does not, you can try refreshing the database by right-clicking on the PSN account in your account settings and selecting “Restore Database”.
Affected games include: Battlefield 4 (PS4), Battlefield Hardline (PS3), Battlefield 4: Premium Edition (PSV), Borderlands 2 (PS2), Call of Duty: Black Ops II (PSP), Call Of Duty: Advanced Warfare (PSVR), Dead Rising 4 (360), Destiny (PS5), Doom 4 (PC), Doom (PSN), Fallout 4 (Wii U), Far Cry 4 (Xbox One), Gears of War 4 (X360), The Witcher 3: Wild Hunt (PS 4), and XCOM: Enemy Unknown (XBO).
This is a known issue and is resolved for PlayStation 4 and PlayStation 3 users, but PS4 users can expect a patch coming in the next few days.
