[Solved] Mesh won't import

Hi. I'm trying to import a fullbody I just finished in s4s (star) but after the loading it doesn't show up in the window nor in the LOD0. I started working on this mesh in august and then abandoned it, I finished it these days and tried to import it in a new cloned object cause maybe the old one was corrupted, but even appending it to the new one doesn't change the result. Is it a bug or am I doing something wrong? I don't think I ever had this problem in recent years.
