Thank you for getting back to me...it's 2021 Pro.

Maybe I should mention that I can open the primary business company file (the one that our Intuit acct is tied to) still but can't seem to open our LLC file.  

It's been suggested that I need to "direct QB to the file" as opposed to trying to "open previous".  However, I did use the "restore backup" function that still had the same outcome.  Is it possible that our dsktp sftwr has been altered in some way after migrating that company to online services making it non functional in other respects?

Regards,
