Restart Steam and/or Restart your Computer.

I did, that didn’t work at all.

delete Clientregistry.blob and retry (doing what DatMeg suggested)

Nope. Didn’t work.

Reinstall Steam?

When I have this problem, I click Ok, then close steam trough taskmanager, and restart it. Then it works again.

Reinstall Garry’s Mod or try deleting clientregistry.blob again.

Done

Done.

Nothing worked…
