Forum:My Fallout: New Vegas Wont Install Properly, Someone Please help!

Hi there, could someone help me with my fallout: new vegas. Heres the problem, a little while ago i deleted the game data from my ps3 and then tried to re-install it again. But everything seems normal once it first starts to download, until it reaches around 79% and just stays there. Ive tried waiting a few hours to see if it continues downloading but it just doesent, can someone please tell me how to fix this? thanks, Owen.
