Hacking EZ Flash Vi doesn't work in DS

[x66x66]

I have an original fat DS. For a while now, my EZ-Flash Vi isn't being read in my DS. It worked for a long time, but then suddenly stopped. I don't know much about flashcards so I don't know how to fix it, or if it's even fixable.

I would appreciate any help!

Assuming you were not trying to update it or something like that the usual cause for this is contact issues- clean the contacts on the EZ5i and if you can your DS as well (cotton bud/qtip and some alcohol or cleaning solution for the things you can find around the house).

EDIT: I think you're right about the contacts in the card. I tried cleaning it, but no luck. Is it possible to be internal?
