I ended up restoring my settings by copying both "AppData\Roaming\logioptionsplus" and "AppData\Local\LogiOptionsPlus" from my old profile. It is great that this method works. I have no idea how to use the "backup" I've created earlier (in the old Windows profile). I assumed those settings would automatically apply once I log in (or6 better, would be stored on my devices), but it just doesn't work.
