Re: steam doesnt update sin
Answer from the above thread:
If your update is stuck at 48%, like it was for me last night when I got home, right-click on "SiN Episodes: Emergence" in the Steam Games List and pick "Pause Updating."
Wait five seconds.
Right-click on "SiN Episodes: Emergence" and pick "Resume Updating."
It's a glitch in the Steam client that has been reported to Valve.
