I recently downloaded Rock Band.cso and I played it once then I hit HOME and then it shut off? Then when I turned it back on The CSO wasn't in my Game folder anymore? But I hooked it up to the computer and the cso was there? But The psp for some reason can't detect it anymore. I don't understand I played it once so it DOES work???

Please help me.


And YES I HAVE CFW 5.00 m33-6
