External Burner Problem

I own a Liteon SOHW-1693SX. My barracks had a power outage. After that i tried to make some backup and ended up making 4 coasters. It gave me PMA update failure. I tried to update the firmware, but when i double click the flash exe nothing happens. Now it gives me session fixation error when I try to burn. Is my burner dead? :doh: :sad:
