Hiya, I downloaded a demo from the psp store for the fist time yesterday and the demo wouldn't boot. I tried booting cso/iso/umd games and they also wouldn't boot. Earlier that day I had installed popsloader. So I thought either of those could've screwed it up however I tried disabling it, running a game, and it still didn't run (however my pops game will still run but probably because it's in a different mode). They go to the psp logo, give me a black or dim screen then turn off. Do I need to reinstall my cfw? If I do will I need to run my old nand backup then upgrade or can I install right over the top of my current 5.00m33-6?
