That scene isn't supposed to be playable during demo.

Ah is the voiced version a demo? I have bought the full game unvoiced as well, but I've never had a problem with anything regarding error messages until recently. 

No, the original poster's error was because they play demo version (and that scene isn't supposed to be playable in demo ver).

In your case, I think it might be because you load older version of saves.
