If you are playing from a save where you are in the bannered mare, just exit the bannered mare before checking this mod.
I was careful to avoid that. I always start in Whiterun, outside the Bannered Mare before entering and attempting once more to get the quest started. I've tried it several times, but none worked.
I forgot to mention that the dialogue gets stuck on the final part. After her last line, thanking me for offering to help (I think), the option I'd selected (something along the lines of "I'll help you", I don't recall exactly what it was) still shows up in grey, and clicking on it or pressing "E" doesn't do anything, forcing me to exit dialogue with the TAB key. Maybe this is relevant somehow...
Thank you for the quick response, by the way!
