Gaming Patapon 2 error

[Maplemage]

Okay I downloaded patapon 2 like half a year ago, and then like 3 months after that it got this error and it doesnt work so I try the game today and well when I run it, it says
"The game could not be started.
(80020148)"
Please help me, my System Software is:
5.50 Prome-2
Im pretty sure its not a bad dump because I played this game before and now it has the error >.> thanks for the help.
And its not a UMD.

I did a search thats almost the same >.>

I found this:
-If not, it is probably a config error/bug and 99% of the time it will be fixed if u "delete flash1 and reset settings" in Recovery>Advanced.
should I do it?

It's probably because you played it under GEN-D3 and then switched to prometheus? Oh, it's also Prome-2, you could always try downgrading to D3 to test it, or upgrading to Prome-3, which should fix such problems.

Im formatting my PSP, now adding everything back in ill post results when finished.
Edit: Formatting didnt help.
