I need some help with my PS3. Recently I bought a game called LittleBigPlanet, had fun for an hour or 2 before updating it. Now after updating it, I played the game and noticed that there are pixels blinking, not just small ones, but obvious ones. This only occurs for LittleBigPlanet. Also, after trying LBP, I tried inserting other games (FF13 Demo) and found out that I can no longer play it. Anyone have a clue on what is wrong with my PS3 and how can I fix it? Its Region 2 by the way.

Thanks in advance.
