PS3 owners you bought Resident Evil 6 through PS Store and pre-loaded the game have been experiencing problems with some not being able to boot the game up after installing the day one patch.
The solution is rather simple, delete the game and download it again, and it should work fine. However, some issues remain and players who bought this version won't be able to access RE.net or play online with players using the disc version for now. This will be sorted with a patch soon.
