aston simba 202

[best4less]

hi
i have a aston simba 202
when i put in a card, real or a sub
i get a error message

upper card reader error

and i get no pictures
i do how ever get what ever free to air
pictures that are avalible at the time
but i dont even need the card for those which is normal
i have tried the cards in another hyundai 1000ir box and
they both worked using a aston cam

is there some thing iam missing
or do i have to pull
box apart

cheers
