Your MicroSD may be corrupted, or a bad USB adapter for your card. Or your card might be set to read only (a switch on the side of your adapter?)If you have access to a different USB adapter, try it. Or a different MicroSD.

it worked last night

i took it out and put it back in and yay it worked

Are you using a cheap USB adapter that came with your flashcart?They are generally poor quality (cheap) build, even ones from quality flashcarts. Must not be making good contact with your MicroSD card.

yeah it looks cheap
