800200D9 Error Code

I got this when trying to load a Patapon cso. But it gives me this code and says Game cannot be started. I Did mess with a slew of settings in Recovery mode after I played it, but I know I changed everything back the way it was. I activated wma playback and the flashplayer too. Any ideas?

I'm assuming that you wouldnt make the amateur mistake of setting the ISO mode to normal with no UMD?

Nope, its set to M33 Driver .

I've tried Normal (UMD Required) as well.
And SONY NP660 or w/e too.

And u installed 1.50 kernal and switched it to that?

What? I've had the 1.50 kernel for weeks and I have played Patapon on my psp since then.

i dont think that would have anything to do with it either

Yea, the cso just goes in the ISO folder so it doesn't need a certain kernel.
