Corrupted file

My NBA doesn't start. I found out that it is because of some corrupted file. I changed few last modified files to original but the game still doesn't start. How to find out which file is corrupted?

Have you tried changing roster file in "Saves" folder?

The problem is not with rosters

Maybe your .exe got corrupted. Check your AV reports and look at their chest (or whatever name it is in your AV).
