How to Play an Audio File

I just purchased a Zoom H5 and it came with Wavelab LE. I downloaded and installed it. Opened a file. Click play and nothing plays. I downloaded the 800 page manual and read about playing files and watched You Tube videos. Click play on the Transport bar. Nothing plays. I feel silly, but it can’t be that complicated. I have tried my cursor in different places, highlighted sections. I cannot just play a file. I am use to audacity. I click play and it plays… Can anyone give me a hint ?
