What is your program, Photoshop Elements 13 or Premiere Elements 13? What computer operating system? And, are you creating a slideshow in the Elements Organizer 13 Slideshow Builder with planned burn to disc in Premiere Elements 13 Editor? Or, do you not need Premiere Elements Editor, since you will be satisfied with the AVCHD.mp4 720p or 1080p exported from the Slideshow Builder?
On top of that, have you updated your programs from 13 to 13.1 yet?
Where is the slideshow getting hung up - where is it running when this happens....
a. Elements Organizer Slidesshow Builder preview
b. In Premiere Elements Editor after you have found a way to get the AVCHD.mp4 slideshow imported into the Premiere Elements Editor?
What are you putting into this slideshow - what formats and how many?
