Error 0x80020146 loading/starting pspsio.prx?

So i bought a Go Explore GPS and find out that the maps are out of date :( so i tried to find a solution to this. Many talked about MapThis.

A friend of mine has updated the firmware to 5.50 GEN-B and now i am trying to install MapThis. I have moved the map to my folders in the PsP but when i start i get a commandline that says
"Error
0x80020146 loading/starting pspsio.prx"

any ideas what to do? All i have done is moved the mapViewer-map to a subfolder under /game in my PsP. I have used the 3.xxx folder for the 3.xx firmware but that should work with 5.50 aswell?

and i have nonne of the 2 prx files. do i need them with 5.50? havent found them anyway..

sci4me,

you need to have this structure on your PSP:
ms0:/

PSP/GAME/

mapViewer/

maps/

_map01

_map...

system/

... sys_files ...

EBOOT.PBP

sioprx.prx

I don't know about this error or this file. Never saw that before. Confirm that you has this structure. If you have... I'm sorry, but I think I'll not be able to help.

I also get this error after updating!

Anyone got a fix for this? I'm stuck as well.

PSP fat
firmware 5.50 Gen-B
MapThis 0520
GPS Module PSP 290
Kernel 5.xx

I'm trying to run the the application from GAME 5xx folder. I have extracted the two .prx files (usbacc.prx and usbgps.prx) from firmware 5.00

Help... puhleeeeeeez!
