Hello, I am using a psp 1000 running software 3.52 M33.

I have tried updating the PSP following this young lad's direction http://www.youtube.com/watch?v=bij-omUaKw0


when I click on "Update ver 6.39" in the game folder, the psp logo/sound pops up but then I get an error

""the game cold not be started (80020148)"

Please help me get through this problem so I can play The Legend of Heros!

Thanks.
