My fiance was playing a psp game after using the exploit on my 3.50 Vita and it suddenly crashed. After trying to restart Ape Escape she was given a message that she was required to re-download the game from the PSN store and it would not start after that. I was able to get around the error by putting the Vita in flight mode and turning it off then on again. I just wanted to mention this here in case anybody experiences the same. Don't panic
