'Serious error' enabling disabled tracks

Hey gang…

I disable all my tracks in my template until I’m ready to use them. I’ve never had an error until two days ago when I added Modern Scoring Brass to my template. No other tracks have issues being enabled except these. MSB is RAM hungry, but I’m not seeing a spike in RAM usage when this occurs.

I can ADD new tracks with these instruments without an issue, but if I disable/ reenable I get the “serious error” dialogue.

It’s the cash log .dmp file that’s needed.
