There are several threads already here about similar problems. Take a look at this post and see if the problem is with your .PHD project file. This post is similar and specifically about PhD11, but isn't yet resolved.

I don't see a save button on this program, only the close button on the top right. Is this the proper way to shut down for the day after working in the program? I was able to open the program with the backup file, it worked , but then somehow, the backup file got deleted. So I have to start over, reimport all the photos I was working on. And change the default setting for backup, to every time I close the program.

The answer to your question is that PhD is unlike most other programs. It saves everything you do in the project file without you needing to save your edits in a separate project, like you'd do with Word or PowerDirector. The good news is that closing the app is all you ever need to do.

I'm glad you saw how to make automated backups, although if you store the .PHD file in a OneDrive or Google Drive folder you'll always have access to older versions if you need to do a restore. I found that out by fortunate accident as PhD had defaulted to saving the project file in my OneDrive folder. I mentioned that in one of the other posts, and it's saved me many hours of headache and heartache. when things went wrong during an upgrade or some other glitch.

When I started using this program, I was having major malfunctions after a couple days use. Then I changed the project backup default to every time photodirector closes. Since then, I have had no problems. Even when I have several Tiffs at 800+MBs. My guess is, that the program needs a little time to save files before closing.
