Unable to Cut/Silence/Split/Join

I have Audacity 2.0.6 on Windows 7. Installed with the .exe installer.

It had been working fine when I last used it over the weekend. This time when I’ve used it, though, I find that I’m unable to silence the audio in any selected segments of the recording, as well as anything else in the related menu. I have properly stopped the recording (I did not hit pause), I have reinstalled the program (had 2.0.3 when I first encountered problem), I have reset my preferences entirely. I have created a new project and still have the same problem. What should be my next step to fix this problem?

You’re going to kick yourself :wink:

You’ve gone too far down the Edit menu and are looking at the “Labelled Audio” sub-menu and there are no labels in your project.

A little higher up the Edit menu is the “Remove Special” sub-menu".

Indeed I am going to kick myself. Thought I was going crazy for a bit, there. Thank you!
