This is a very old and "easy-to-solve" error, just like riding a bike. Learn it once and never forget how to do it.
Anyways, to come to the problem itself, well sometimes it just solves by it self if you just quit and restart steam. But sometimes it just like to drive you nuts and just does not go away.
1. You have to know your password for the next steps so be aware and if you do not know it try to remember it.
2. If you know your password, go to your Steam folder and delete the following files:
SteamUI.dll
Steam.dll
Clientregistry.blob
3. Start Steam and wait for it to update, as soon as it is done, login. You should not have any problems with the Validation errors.

Dies ist ein altes und einfach zu behebendes Problem. Man muss die Lösung eigentlich nur einmal lesen und weiss es dann immer fast so wie Fahrrad fahren.
Also zur Lösung
1. Du MUSST dein Passwort kennen sonst bringt dir der Lösungsansatz garnichts.
2. Wenn du dein Passwort kennst lösche folgende dateien: (sie befinden sich im Steam ordner bzw. C:\Programme\Steam\)
SteamUI.dll
Steam.dll
Clientregistry.blob
3. Starte steam neu und logge dich ein.
