Importing files in Fruity Loops

Hey, I’m new at this board, my name is Chris and I have a question about fruity loops. I am currently using Pro Tools M-Box to record stuff and want to put the vocal tracks i record into fruity loops. How do you import recorded tracks (.wav file) into fruity loops? I tried and I could never get them to play. I put the .wav files into the Recorded Folder on the left side tool bar, but it wont play when I click on it. Can anyone help me with this problem?
