SD card not reading

Just had the gmax 1.5 shipped to me, not new its about 6 years old. Got a new SD card for it and when I insert it into the printer the main screen acknowledges the card has been inserted but when i press the knob to go to the next screen it says "No SD Card". I've tried blowing into the slot to clear out any debris and power cycling the printer but nothing has worked so far. I've also tried reloading the gcode and making sure I eject the SD card so it isnt corrupted.

What should I do?
