hey ppl. i just got a 2nd hand psp and tried playing the new football manager 2009 on it. it says i need to update but i get the error dadadada
i've tried or so i think to format it bak to version 1.5 but with no luck, get the error "Open error <read>" in cmd when running the roll back program. i have no idea what i am doing with a psp as am a bit of a technophobe and everything i have seen regarding this dadadada error hasnt helped. ne 1 can help me out there??
