Hi Alain, I just spent 2 hours building a slide presentation for my Sermon for our Church service tomorrow morning! Everything was working fine (had a few crashes but like always I save as I go along). To finish of the presentation I downloaded and added some of the transitions you have on the site, I went through each slide and added the transitions as I went. Then I saved the presentation. It crashed again. Only this time I cannot reopen the file. I get the same error over and over again “Unable to read beyond the end of the stream”. Pleases help!!
