Acekard 2i broke after pokemon black 2 patch?

Hi all =)

So today, I was really excited because I finally patched pokemon black 2 (or so I thought) after loading it in my 3ds, my acekard would first pop up with the yellow loading... then the loading turned red, and in the blink of an eye, it said FAT. Error in red, now it refuses to get regonized by my two dses, as in, the ds wont regonize the card to be more exact, I formatted the SD card in it, and before that, tried to delete everything manually, still cant seem to get it to work though :/

Anyone any ideas?

 

2 things

1. Format the microSD using the Panasonic SDFormatter, if that fails then:

2. Use a different microSD

 

Ive read about other people having this problems and they said they had to reflash their cards
