Games N Music DS Help

[Colton]

So uh, I recently got Games n Music DS. Having fun playing Bomberman 2 and Earthbound anywhere with the SNES emu now. But, today, my Micro SD card somehow got a Write Protection thing, so now I can't write, move or delete anything on it. However, I can still use the files perfectly fine on my DS, and I can still write save states on the SNES emulator, but I don't wanna get bored. Any solution to this problem BESIDES buying a new Micro SD Card?
