I've had tried it with the Dive Sound mod installed and uninstalled. Problem remains, but see below.

I found thtat it was this that was causing me the problem m8 and I never installed it on this new rig and it works just fine.

As you've got the P-51's Merkin running try play with the other 'prs' files and make slight adjustment to see if this works m8.
