I use a card reader and put a camera memory card in one of the slots and it had always worked. I plug it in my computer and it appears on the screen and I can convert vids/photos onto my computer. I even did it today and it worked but for some reason when I tried plugging it in my computer nothing happened. It didn't respond! I tried plugging in another computer, didn't work. Tried blowing in the slot to get rid of dust, didn't work. Tried cleaning the card, didn't work. Something wrong??? I literally did it earlier today and it worked but all of a sudden nothing's happening.
So now I can't upload an photos and vids from my camera.. Help!!
