Sound isn't working in harmony essentials

I recently started the trial version of toon boom harmony essentials and every time I import sound it doesn’t work and where there should be a waveform it is just a single black line!

I am extremely disappointed with this software and hope that someone can help me out!

I have tried reinstalling toon boom and other suggested things but nothing works, if anyone has any idea what I should do or have had the same problem please comment below!

I hope toon boom can fix this very soon because I was looking forward to getting toon boom for my birthday and had bought a graphics tablet just so that I could animate!!!

What file format are you using: wav, aif, mp3 or else ?
What’s your Sampling- and Bit-rate ?
