HL2EP2 Error

Error says -

SteamStartup() failed: SteamStartup(0xf,0x0018E584) failed with error1: failed to take master pipe connection lock

Would anyone know what this means?

Did you try restarting Steam?

If restarting Steam didn't help, here's a thread (http://forums.steampowered.com/forums/showthread.php?t=816997) about it. Post #5 seems to have the solution.
