When I checked the progress this morning at 7 am, the temperature had cooled down to 64 degrees, and after 2 minutes of observation, no bubbles appeared in the airlock. I'm trying to raise the temperature in the room now, and have also covered the primary fermentation container with a blanket!. I'll watch throughout the day, and if the temperature goes back up and still no bubbles, I guess the next step will be a google search on "stuck fermentation"...
