Just tried to create a slideshow and it continuously crashes LR6. It appears to try to create a preview of a slide that doesn't exist. For example, I tried a 25 picture slideshow (to troubleshoot the problem) and the message window said something to the effect of creating preview for slide #26 and the crashes. Obviously there were only 25 slides so there could be no preview of slide 26. I'm not running GPU accelerator, and went back to LR4.4 with the same pictures which created the slideshow as expected and always has (worked). Any ideas? Should I just run the LR6 installer again? Uninstall LR6 first and then re-install? I have already installed the update 6.0.1 after this problem surfaced, but it did not help.
