Commander screen is blank after update to V1.018

  • Hi all,
    I just updated my commander to V.1.018 from V.1.016, after the commander shut off by itself, I then waited for 2 minutes to turn it back on.
    But the screen is blank and nothing on it, all buttons don't work. What do I do now? :o
    Thank you.
    Regards
    Andi
