Lightroom: Exporting Slideshows works inconsistently

I've just installed the latest update to Lightroom.  While I'm pleased to report that I can now export 1080p videos that combine both horizontal and vertical images, it does not work reliably.  In order to make it work I have to quit Lightroom and re-open the program and immediately export the video.  If I'm in the middle of a work session and then attempt to export a video the export fails every time.  It will ONLY work if I quit and re-open the program each time I want to do an export.  Can I get a reply from someone at Adobe?

A Comiter,

Can you provide us with: 
1. Mac or PC?
2. OS version?
3. Please go to Help>System Info... and get us the exact version number installed and running on y our system?
4. Provide us information about RAM? Free Hard drive space?  Screensize? Video Card Memory?

How long are the videos in seconds? How many individual slides in the video?

Hopefully from this information we can spot where the hang  up is and help you out.

Hi, Thanks for your reply.  To answer your questions:

- I'm running Lightroom on my new MacBookPro.  Previously had the same problem on my MacPro desktop.  

- Typically, the Slide Shows run about 12 minutes in total, with both vertical and horizontal images,  about 80 to 100 separate images, and include music in the background.

- Prior to the latest Lightroom release I had to use a very old version of Lightroom to export a slide show.  With the latest update I have to quit the program, re-open the program and immediately export the slide show in order to get it to work.  Once I've exported one slideshow, I cannot repeat the process unless I quit and re-boot all over again.

A Comiter, 

Nothing stands out in the information you've provided (thank you btw).  On a similar system, I am not seeing the same issue as you. I can create a second video without having to restart the system.  If you downsize to 720P for a test, can you make more than one video without restarting?

Hi Rikk, Just tried what you suggested.  I started with a 720p video which worked fine.  I followed that with a 640 video and that worked as well.  Then I tried to do another 720p and as with the 1020p videos the progress bar didn't move.  So, same problem with 720p.  Did I describe the video before? It has 80 photos, most are verticals and a few are horizontals and the files are dng files taken with a few different high resolution cameras.  Anything I should be changing in the Lightroom Preferences? Any other suggestions?  Someone must be aware of this problem because the previous version of Lightroom didn't work at all - I wasn't able to export even the first 1020p video.  I had to go back to a much older version of Lightroom to get it to work at all.    Thanks.

I am passing the information along to engineering to see if they have any other ideas. I've tested on two MBPr's so far with as similar a test as I can manage and am still able to create multiple videos. When I hear something back, I will let you know.
