So, I was installing Killzone Mercenary using vitashell. It reached 99%, and then there was an error message which I unfortunately did not write down. The game does not appear on my homescreen. And upon checking my memory card, I now notice the 3gb is missing, which is basically the size of the game (or 99% of its size, I guess). So... does anyone know how I can navigate to the correct directory to delete these partially installed files? And any ideas on why my installation failed (I know, I should have written the error number down. Sorry)?
