Thanks for the file. i am running OpenLP 2.4.6 with OpenOffice 4.1.5 and the file works in both OpenLP and OpenOffice...There must be an issue with LibreOffice and one of the transitions in the file. I did try the file on a second PC with PowerPoint on it and noticed that the file uses a cube roll transition....but OpenOffice did not show that transition....I wonder if this transition is supported in LibreOffice....<br><br>I know this is not much help....sorry
