Error 80020148 - I've tried everything!

[takutosuki]

Hello,
I've "gotten my hands on" Kingdom Hearts Birth By Sleep and I thought I'd be able to play it since I recently upgraded to 3.90 M33-2. I have a PSP slim. I've had 3.72 (I think it was) until very recently, and it wasn't me who installed the CFW from the beginning.

But no, I cannot play my game, I get the "Error 80020148". All other games work. All settings should be okay. I've tried homepages and youtube....

Here are some images of my PSP and settings in it.

I've tried set the "game folder homebrew" to "1.50 kernel" too, and tried "Sony NP9660 no umd" as well as the "m33 plugin no umd" (or whatever it's called). I've tried all that was on that list, together with both 1.50 and 3.90.

Whatever should I do? Is there anything else I can do?
Could my file be broken?

Thanks for any help at all, any suggestions.

"solved".

Kingdom hearts birth by sleep is not working for ANYONE, apparently. >_>
