There's a guideline pdf in the downloaded zip file. These are the steps (copied from the PDF): 1. Insert the AK3040Pro MAX into the computer (or adapter), open Start.bat, select “y”, and press enter. 2. Upgrade started, wait for completion (approximately 1 minute) 3. Upgrade completed, upgrade...

I can confirm that after updating the AK3040 Pro Max, I had no more cut offs with Lossless audio!

If you haven't already, I suggest you contact their support at service@meppfun.com. The more feedback they get, the more likely they are to fix it.
