NightFallNews has its own Support system, it is on the bottom right hand corner of their screen,
They will require the completion number of the slideshow you are inquiring about, this was displayed to you after you completed the slideshow.
If your inquiring about payments for a slideshow you did, please wait 1 hour, they do pay, but a little slow.
You are allowed to do 5 slideshows per day.
After slides 20 and 40 you will need to follow onw of the featured stories to continue.
TimeBucks support can not fix this issue for you.
