Cant see the soundfile anu longer. Whats wrong?

Hello. Suddenly the files that I record with the mic or try to import doesnt appear in the timeline. I tried to check to see f I closed something by mistake, but I cant fint any button to put it ther again. It worked perfectly yesterday and I just had to push the savebutton , and the file appeared directly in the timeline. . It doesn´t help to shut ariculate storylinte of or start at new project. It does record, though i can listen to it in the editor...i just doesnt understand why it suddenly seems unable to import it to the project. Can you help me? Grateful for any help
