exported mp3 file in itunes has no sound[SOLVED]

Audacity 2.0.5
Windows 7
Successfully transported from LP played on usb turntable. Can playback in Audacity with sound. Added track names no problem. Exported mp3 files for all tracks and saved in computer folder. Itunes recognizes files in folder and displays names. No sound when file is played in Itunes.

See if this resolves the problem: http://manual.audacityteam.org/o/man/faq_playback.html#usb

worked like a charm. Thanks!
