new update deleted everything I ever created

[noniiiieee]

Hi! I need help

I just now updated the programme, since it wanted me to, when opening it on my laptop.
I did like they told me to and after a bit, I noticed that every house or plan I ever did, was gone.

How can I get it back?!

I use it for job work, and there was a lot of important stuff and now it's all gone, I'm devastated...

Sweet Home 3D updates certainly don't delete SH3D files, so your files must be there somewhere on your disk.
What version do you use (see About dialog box)?
