My Acekard MicroSD

Hello,I recently got an acekard and it came without the computer connecter.
I had the miniSD so I put it in my card reader since it wouldnt work in my DSLite.
So anyway I realized I had to format the device and ended up using a panasonic one. However when I went onto my Card Reader the folder that connected the computer and microSD were gone. I really need help...
