Flashing Green lIght of doom

I have a My Book LIve and it worked fine the first time I used it. I set it up and uploaded all my data in 24 hours.

The next time I booted up it stopped working.

On closer inspection the front light flashes green continually. I am sure this has been addressed in here somewhere but what are the things to do to reset it?

go to bed and forget about it.  flashing green means its probably building thumbnails and building databases.  You could try to uncheck wd2go, mobile access, itunes, etc to see if that helps.  or even disable twonky.  but then, you can’t really stream anything.
