If you have a song file where you consistently hear the thump sound first thing to do is click on each track snowflake button to "freeze" the track. You don't want a track to regenerate and lose the thump.

Attach the song file to an email addressed to "support@pgmusic.com". In the email provide a description of the issue. Something like "bar 30, beat 4" has a loud thump on the Realdrums track".

You may, or may not get a response beyond an automated message received. However PG Music is pretty good at addressing multiple RealTrack\RealDrum issues in one update so you may find the drum track works after an update.
