2,626 entries listed.
Steam might have a unique method to bring it back up.
Tap the arrow at the top of the clock area, notice the steam icon, click once and then exit Steam, after that reopen it... LOL
Are you encountering the warning that reads like "unable to reach rockshit servers at this time..."?
Exit the program and begin again.

Just got it all set up!
It took some time but I'm here now, and once you're in, just stay.
