Sims 4 studio wont import my mesh?

Hey guys I'm new here and don't want to sound stupid so I'll try and be as detailed as possible, I was following a tutorial on making a table and I followed all the steps the cuts are the same and everything so once finished I wanted to see how it would look without the texture, so I went to import mesh and i got this error notice. 

The Sims 4 Studio - Version 3.1.6.3
