The following may look like a wall of text but I urge everyone, especially, anyone having problems with CK NPC dialogue or any skilled CK user to read through and respectfully ask any one that can to help. It would be great too if this can be passed on by a forum mod to the dev team!
Having followed the ‘GSQ01’ tutorial1 to the letter creating only what it says to and doing only as instructed and having got as far as creating the topic and yes / no answers and linked them, I have come across a problem in the CK / game whereby Dialogue given to an NPC in the CK does not appear in game. This is just before starting the scripting part of the tutorial.
Though the problem is remarked upon in another thread2, I am posting this* to try and get an answer as to how to fix the problem as it would seem the other thread has slipped down the forum thread list out of sight (maybe out of mind to a lot of posters too!)
The problem;
With the CK running, load 'Skyrim.esm' data and get to work on the 'GSQ01' quest in the CK dialogue tutorial.
Before starting the script part of the tutorial, the dialogue should now work in game. The dialog working point is made in the tutorial;
'Now, when the player selects the prompt "Do you need help with anything?", Bendu will say his line and then present the player with another list of choices based on the links from that topic. The choices will be listed in the order they were linked from that topic.'
The dialogue does not work though and In game testing goes something like this;
Scene: Inside Mixwater Mill Workers House.
Actors: Player Character (PC) and Bendu Olo
Conversation:
[E] Talk - Bendu Olo.
(Press 'E' to start conversation.)
PC > Bendu Olo - 'Do you need help with anything?'.
(Press 'E' to submit question.)
NO RESPONSE FROM BENDU OLO.
PC > Bendu Olo {1} - 'Sure, I can do that.'
PC > Bendu Olo {2} - 'Sorry, not right now.'
(Select either option then press 'E' to continue conversation.)
NO RESPONSE FROM BENDU OLO.
PC > Bendu Olo - 'Do you need help with anything?'.
This is always the same when the player character talks to Bendu.
I have CK set to 'Run as Administrator' as someone suggested this in a different CK thread - sorry I did not bookmark it so no link.
Though I have a fair bit of computing / IT experience, I was deliberately following the tutorial as the CK and 'modding' in TES are new to me.
I have looked and looked for anything that I or the tutorial may have missed to no avail.

I have tried removing all traces I could find of the ‘GSQ01’ quest from creation kit, game and saves (D:\Programs\Steam\SteamApps\common\skyrim\Data) then restarting PC. This has been done each time I have tried to make the dialogue work!
I experience the problem in game with the CK still up and running and with the CK closed. I tested both scenarios just in case the error was caused by two applications trying to access the quest file.
I have also tried (succesfully) to verify the Skyrim game files through Steam.
My basic PC stats are in my sig for reference.
PLEASE! I am asking if anyone knows why this is not working, a work around or how to get this to work as it should. If that person is you, please share!
If it is that I'm missing some step or something, I would be more than happy to be corrected.
If this is a CK or Skyrim issue then I would be put off having to wait for a fix but would bide my time. (Hopefully not for too long.)
Either way, I feel I do not wish to download any quest 'mods' that may be badly affected by this issue or continue with the CK with the potential of releasing broken 'mods' to the community.
Thanks in advance to anyone that can give constructive advice on this issue.
