can't edit audio

I recorded the audio in V1.3 but couldn’t edit it, so I uninstalled and installed V2.0. I still cant edit the sound. I have tried everything, selecting and pressing delete, pressing the cut button, pressing backspace etc. When I go to edit drop down it doesn’t even give me the option as its greyed out.
After giving up I went to save the file, but this option wasn’t available to me either as it was greyed out. I had to quit the program to get the automatic response, do you want to save before exiting! Please help

Ensure that Audacity is not playing, recording or paused. It must be “stopped” (click on the “Stop” button) before the menu items are available.
