Hello, @SEGICA
You need to open your measurement file in SeamlyME and save it as .smms to bring it up to date with the new Seamly software.
It seems to me that you have installed a 2024 update of Seamly, so this also needs to be updated to the latest version.
Other than that, I have repaired your file and it now opens on my version of Seamly2D, which is currently 7 Sept 2026, so it won’t open on yours until you update.
There is a link at the top of this page where you may download the latest.
Since you didn’t send a measurements file, I had to create a dummy file just to check that the file opens. You’ll need to point the file to your measurement file when you open it.
Here’s your file back:
