Open the .odt file and save it as a PowerPoint file.....don't worry, if you use the save as menu option this will create a new file. I recommend using a ppt format for office 97. it is an older format and should be stable. If this uploads into OpenLP then you should try to upload the file as an older odt format.<br><br>If reformatting the file does not fix the issue, go into the data folder, shut down OpenLP and copy the presentations folder to a new location. With the folder saved to a new location, delete the presentations folder and start OpenLP. The presentations folder will be created as the program open. Try uploading your original file at this point.
