Wasn't working for me because I don't save my username and password on the computer. The Steam website says you have to log in online first, so I never really bothered. Never though clicking "remember password" was particularly important for offline mode, and the application itself doesn't make it particularly apparent. My mistake, I guess.

But anyway, it doesn't matter. My point was DRM has never bothered me and probably never will. You're certainly allowed to feel differently.
