you can open up the card and try resetting the position of the spring. its just a metal thing that can be easily repositioned. the issue here is that the new ak2i no longer has the clips so they are not as easy to open up.
you could try forcing in the msd card. if you push down hard you may be able to fix your problem. however, you may also cause more issues.
if your ak2i is legit, then you could probably get it replaced. all acekard products have a 1 yr warranty.
