Board doesn't boot?

I just finished writing a simple program to power (D13) and (D12) when pressing the USER_BUTTON, I flashed it and the LEDs connected to the ports didn't light up. I tried switching positions and suddenly the COM (LD1) led started blinking red. My computer doesn't recognize it as an USB device and I have no idea on how to fix this. Any suggestion?
