The home page even showed the first page as the cover in contrast to the original which showed a blank page.
Yes, that's what I expected. My wild guess about the crash issue is that the culprit is the AES 256bit protection. But in fact I don't know what the hell it is. The pdf is protected against certain features (even with a "password") but at the same time you can freely render it...

I've never been able to understand how this kind of protections CAN work... If I can access the content then I can access the content, how can you prevent me about doing whatever I want with it? And if it is encrypted and I cannot access it, then I cannot access it, so how can I render and display it?

Nevertheless, it would be great if someone with full fledged Acrobat could generate a sample pdf enabling this feature...
