Doesn't restarting Steam help?
Nope.
Restart steam, and delete "ClientRegistry.blob" from the Steam folder if need be.
I've did everything they said on the Steam support and no effects.
Steam server was down a few min ago (Steam Store/Activation). So maybe they're doing some kind of maintenance?
It's not happening to everyone.
I'm feeling to re-install Steam
Edit:None of my games works now, not even hl1 engine games
