Troubleshooting Persistent Steam UserID Ticket Errors If you have determined that the Steam network is not down and you are still receiving this error message, this issue is most likely being caused by not restarting after a Steam update has been released.
If restarting Steam does not resolve the issue, please exit Steam and delete the following files:
Steam.dll SteamUI.dll ClientRegistry.Blob These will be found under your Steam installation directory - by default, this will be C:\Program Files\Valve\Steam\ (this may vary if you specified a different installation folder, or if you have moved your Steam installation).
D-E-A-D dead. Stabbed in the face. Nibbled by tiny pirhanas. Mauled by Grizzly bears. Run over by Semi-Truck, three times. Swallowed ignited napalm. Took a 12-gauge to the gut. Ate nitroglycerin and then jumped on a trampoline...need I say more?
