I get the same error over and over and over again after the last update. And deleting the clientregistry.blob is not helping in the long run .. but does work for 1 game .. at least I can play like that for now ...

Hmm, not sure if i have had that or something similar quite regularly since their last update. All i had to do was restart Steam and it was sorted.
