I have a PSP1001 I have CFW 3.52 M33-4 I have mapthis .5.1 and have extracted my prx files, I have read more posts than I want to admit and I have had no luck, when I run the mapthis program with psp-290 it comes up with blue screen saying mapthis loading usb accessory module and then shuts off any help would be unimaginably helpful
