Help needed, its been a while.

Hey guys, I need some help with my psp.

I've recently started playing my psp again, and for some reason, some of the .cso games would not play. I get the "The game could not be started (80020148)" message. But this is only for some games, while others would work.
I've tried changing the drive to the sony or the m33 drivers but those games still won't play. Could it be that my system is too old and need an upgrade?

I got the old school fat psp, and the software on it is 3.90 M33. It's been about 2 years since I've fool'ed around with it, so I don't remember at all how to upgrade or change things.

If anyone know what the problem is, please let me know. If its an upgrade problem, could someone point me to how to do it properly w/out messing up my psp? Thanks~
