HELP! How do I fix a corrupted game file on PS3?

[046]

So over the Christmas holidays there was a sale on the PlayStation store and I purchased Need for Speed Most Wanted (2012) and When I went to go play it it asks me to update it so I updated it. It then says the file is corrupted, then it gives me a code 80029564 but I don't know what to do with it. I then deleted it and re-downloaded it but this time I just skipped the update and then I could actually play the game. Today I went to play it again this time i actually went to the games menu screen to update it because I wanted to play online and it does the exact same thing and gives me the code again what should I do? I really want to be able to play online as-well as single player. Thanks.

delete both the game and the save
check your internet connection , make sure it;s good before you download the game again
make sure you have an online pass included with the game , you can not play online without the pass ( the pass would be included with the digital copy )
start the game and update it before you try playing

if it happens again check your router settings , you may need to port forward to open the connection to the games online servers
