Urgent. Can't open any saved file.

[geraldo]

Hello, a few days ago I had a problem with my computer and had to reinstall windows 11. Accordingly, I also downloaded the latest version of Sweet Home 32. Now none of my .sh3d files open, and I need them urgently. The message that Windows gives me is "can't open...". I'm not sure which version I had before, so I tried installing old versions of the program, but that didn't work either. Please help.

Make sure you have the latest version installed (7.5). You can check the version by clicking Help > About on the menu.
Can you create a new project and open that again after closing?

Yesterday I installed an older version - 6... I created a file with it and saved it. Today I installed the latest version - with it I can open yesterday's file. But the "old" files still won't open. I missed saying something. After I reinstalled windows I changed the user name but I can't believe this is the problem?

Can you share one of the corrupted files?
