I have an Acekard 2i and have been using it with great success, however, recently whenever I plug it into my PC it does not pop up like it's supposed to. And if it does pop up it will not let me add or remove files from it? This happened when I added the newest firmware via my Mac laptop (I usually ue my PC). Did the two different platforms of computing cause the problem? Or was it the way I added the new firmware (Deleted the old file from the card first, then added the new). I tried formatting the card but it is 'write protected' and would not allow me. I don't now what's going on? Technical error with the card or human error with what I recently did? (Also I had a DSi which was updated with the 1.4 firmware. Before the firmware my computer recognized it fine, but after is when my PC started having issues. Does the 1.4 do something to the cards themselves?) If someone knows anything that would be great!
