i assume your card is a R4ids.cn Gold card yes?
Support V4.3.0-10 and NDSi V1.4.4
this mean you card will not work on 4.4.0-10
and 4.5.0-10
you need to check the revision of you card
check the furthest right pin slot on the card
you should see a letter or a number
(hopefully you will see the letter C)
if you have revision C you are in luck but must wait
there is an update coming but it has yet to be released
if you update your 3DS to 4.5.0-10 or 4.4.0-10 your card will not be able to update on that console
so if it is currently working on its DO NOT UPDATE
wait until your cards update is out and you have update the flashcard
only after you have ran the update on the flashcard and it changes the icon to the new one
then you can update your console
