Civil Defense stuck?


PC, seems i got stuck on civil defense mission, got the “to do list” password but dialogue didnt progress , i was hosting got 2 mates and probably one picked up note while i was away, maybe near Therese. Keeps asking to find the password, any red mark in the city left.
i’m missing how to progress or its stuck?
