I have downloaded Hellcat recovery flasher as instructed, it appears in the menu but as soon as I press X it says "the game cannot be started. The data is corrupt". What am I doing wrong? I upgraded to 5.5 accidentally, all I want to do is play films - I use Xillisoft to convert films to PSP format but with 5.5 they still don't appear. Please help.... Many thanks. Slotter.
