All imported textures and furniture disappeared.

Good morning.
For the first - sorry for my very basic english and for mistakes that I make.
Well, let's return to my problem.
I use Sweet Home 3D for a long time. I recently updated this application to latest (4.4) version.
It's okay; very good, new texture tool. Cool.
But when was a power failure in my house, all imported furniture and textures disappeared. In the past, objects never disappeared.
I thought it was a one-off case. I imported these objects again. For a few days everything was fine.
Yesterday, my niece visited me. She accidentally turn off my computer.
My project was recovered, but imported files again disappeared.
What happened? Is there anything I can do? How to restore the imported files?
Thanks for help.

If you have a backup of the private data folder of Sweet Home 3D where imported stuff and preferences are stored, simply copy back its content. Otherwise I fear it won't be possible, and you simply were unlucky. [:(]
If you imported a lot of 3D models, I suggest you to manage them as a Furniture library with the Furniture Library Editor. This will make it easier to create backups.
