It keeps saying disconnected fomr server. Reason: Error verifying STEAM UserId Ticket (server was unable to contact the authentication server)

restart steam and try again.... if that doesn't work then restart your computer, don't know why this happens sometimes but one of the above should fix it

Omg, I just got that shit too.

This is what I done.. search blob on your computer and delete all of it that falls under Steam, works like a charm for me. :D

Thanks Semper worked like a charm.

No worrys.

Awww, I just looked at the steam site and this is what it said

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).
