Is there something in particular that has to be done to get ES2 to update to the Dark Matter release (other than buying the DLC)? 

I pre-bought the DLC back in Jan, and it shows as in Library, and no longer shows as locked. ES2, however, shows no updates, and when I start it, Dark Matter is not among my DLC or Add-Ons, and it is still build 1.5.37 not 1.5.46.

Restart steam and it will start updating.

Didn't fix it this time, but I'll try again in a bit.

Steam decided to update this time. I guess I was just a bit impatient.
