You've set the "Write on PICkit button"? If yes, can you try this? Unplug UIC00A from USB port, press and hold the button, plug in the USB port again. Do you see the red LED blinks? If yes, it's successfully entered the bootloader mode. That means the button is okay. Unplug and plug again to reset the circuit to normal mode.
If these give negative results, you need to send it back to Cytron for warranty. I guess the button is spoilt.
