Sorry for my late answer.
I promise I do the same, I did now it again step by step like you did, showing all the supported libraries in the browser options and when I’m in the folder with the .mod file it doesn’t appear (I downloaded it again like you did also but the same is happening…)
Is there any way that you could send me the footprint with the new format? so I just have to download and copy it to my folder…
I noticed that when I try to save the file in my folder when I download it from this web as you did, in the type of file I can select “Quickfield File” (FEM Software) or all files. If I select all files and keep the extension .mod it is also saved as quickfield file… maybe that is the problem
