I get the request to update to version 1.6 on my ps3, but when I go for it, it tells me I don't have enough hard drive space (I think it asks for 311mb, I have gigs free, so somethings up). One time the screen wigged out and it told me there was an error in the config file, anyone know how to fix this?

Are you sure you have gigs free? Maybe you should delete some old saves, or gamedata for games you don't have anymore or haven't played in long time. But really this sounds more like an issue to take up with sony
