Playlist Not showing in USB

Hi everyone, so I had my old playlist for a club I'm preparing for but wanted to add new songs to it. So I deleted my old one from my USB and try to import the new one. When it would say export it would export the folder in like 3 seconds for 200 songs. Now when I go to my USB folders it doesn't show up. Ill try t o export it again but then says that there already is a folder there. Any help???
