Good afternoon, I have a problem with opening a file I have created on OpenOffice last year. I can open the program, but as soon as I open the file the program crashes. I have macOS Mojave ver. 10.14.4 on my Mac. I can start with a new file and it opens fine. I have been at iStores today and they have downloaded the program on one of their Mac's, the file that crashes on my Mac opens. They have also downloaded the latest OpenOffice onto my Mac. Please help.
