Just installed audacity 2.0.5. No previous versions on this machine. Installed Lame 3.99.3. but Export is not selectable in Audacity. Checked audacity.cfg. No reference at all to MP3 to delete. But Export still remains unaccessible. I uninstalled and reinstalled both audacity and Lame -same results.
Ensure that playback is stopped and not paused.
Most commands in Audacity require that playback is stopped.
Got it. Export works. Thanks Steve.
