The music fade-out is very choppy and it does not matter what time length nor music file format I use.

This happens in the video preview of the project and the final exported version.

There are no other user applications running, 

Any assistance would be greatly appreciated  - I have paid the lifetime price for the product as I really like the application.

My system information:

- CPU = INTEL CORE I5-8250U @ 1.6 GHZ

- MEMORY = 8 GB

- WINDOWS = 10 @ 64BIT
