Q: How do fix the black screen on the Thunderbolt Display

I downloaded the Thunderbolt Display Firmware Update v1.2 last night while working off my Macbook Air connected to the Thunderbolt Display with the lid closed. Everything appeared to be fine, because it restarted and the Thunderbolt screen cam back up and I continued to work through the night. Then I walked away leaving everything as is... They eventually went dark through the night. I tried to reconnect my MacBook Air to the Thunderbolt Display again today, and all I got was the black screen. Everything was plugged in, restarted, shut-down and restarted, reset the PRAM, unplugged from the wall for a few minutes and plugged it back in, I did every troubleshoot I could find on the web.

Then I came across this:

So it appears my versions are not correct? I then tried to re-download the same update and I got this message:

The Display is plugged in to my MacBook air via the Thunderbolt port, What gives? I need help please
