No need to apologize! You're fine. Just trying to make sure we eliminate all of the easy stuff before we move on.
I wonder if this is a similar glitch to the one someone else reported where they were unable to launch dialogue with an NPC later in the game.
I assume that you've already exited the game and reloaded it from the last save. You can also try loading from the save prior to your last save to see if that makes a difference. There have been a few people who have had glitches like this resolve when doing so.
Something else that has worked for some people when they encounter weird glitches like this is to reset your settings. I'm going to quote khh from another thread here (because I don't trust myself to explain it without forgetting something).
One thing you can try is to reset the settings. As far as I can tell there's no easy way of doing it.
Press the windows button + R, and you will see a run box appear. Type in regedit.exe and hit enter. Nagivate to the HKEY_CURRENT_USER/Software/Red Thread Games/Dreamfall Chapters
There you will see a lot of options for the game. Mark them all and press delete on your keyboard. A warning message will appear, press yes. Afterwards only the default value will remain in the folder.
When you launch the game again it should have default settings for everything (Don't worry, this won't affect your saves).
Some other people might have some other suggestions, but this is what I can think of for right now. Morten / Team RTG may have to investigate. If this is the case, you may need to provide some logs for them, but let's try some of this trouble shooting first.
