Hacking having issues with the card showing up lately

[gooface]

I have a R4i 3DS (legit one) and lately I am having issues with it showing up on my DS lite and New 3DS XL. (to the point at sometimes the 3DS locks up when the cart is inserted) it will randomly show up at times on both consoles and work but the majority of the time it isnt showing up. (tried a 8gb and 32gb card in it and have the same results)

Any suggestions? I only bought this card back in May.
