Hi thanks for your answer, I have found the solution, so for anyone who has this game on playstation 3 here goes: apparently there was a software glitch with this game so when you had a certain amount of data saved on your hard drive the message" you require 419MB of free HDD to load this game "would show even though you really did have enough space to load it anyway, what you need to do to solve this problem is add or delete 500MB data to/from your hard drive........it solved my problem, I can now play the game.
