I have GT 5 XL edition for and it was working fine I used it last night on multiplayer. I also switched some cars to favorites and created a new track. Then I updated my PS3. This morning when I got on it is all starting up ok but then I reach the screen that asks you if you want the 8 gig download. The button on the screen that says yes is flashing along with the mouse. I cant do anything, cant click yes and i cant move the mouse to say no. It also stops making sound at that point. What do I do?
