thanks for the response. I couldn’t find anything in the manual about how to access the backups, but, finally figured it out. I did a search for “Backups” under the File tab on my computerand found them in Documents>Media100i Backups.
I then opened the project and under File > Open > navigated to the last backup in my documents>Media 100i Backups and it opened. Yeah! I am now rendering the transitions 5 at a time until I find a glitch which might be the corrupted file. Thanks for your help.
