I encountered a little problem with my last project which would not play on the LF1 . . . just a red flash after hitting play. This project has 31 slides which were duplicated and edited: I didn't change the names of the layers so the software automatically named the slides "copy of copy of copy of copy . . ." - the slide names got longer and longer and at some point the LF1 couldn't parse them.
Once I renamed them sequentially the project rendered and played just fine.
What is the character limit for a slide?
