The sounds like, for some reason, the PDF library is unable to load the files, or something else is failing internally. So the first thing to try is to go to Settings->Display Settings->Render Preference, and try changing it to "Speed". This will utilize a different PDF library. If that one also exhibits the same behavior, can you please let me know either what version of Chrome OS you are running, or if you dig into the Android settings, what Android OS version the device is running?

Thanks,
Mike
