Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing issues loading your file. Could we get more information on the issue here. You recently installed an update and it wouldn't load your main file? What happens when you do try to load it? Did the backups load properly but not your main file?
With more information we'll see what steps we can take to diagnose the issue you're having. Once you get the chance please let us know more.
Thanks,
Quicken Francisco
