have had the aiptek AHD T7 pro for a few months now last week though I went to use it and it keeps coming up with a message saying that the memory is full, (the SD card is empty) when I plug it into the computer it says it need to format, but cancels before its done saying windows was unable to complete the format. the card works fine with all other software and even on its own plugged into my computer, just not with my camera. please help
