Help! After upgrading to V1.013 firmware today, my DR750S-2ch video is upside down! I tried everything, including reformatting SD card, powering down, reinstalling update again. But changing the setting still does NOT work. It is stuck upside down! My camera is now useless. I would like to downgrade to V1.011 please! I had no problems at all with V1.011. Is there a link to download that version? Thank you
