No longer works, even after changing function names to the new ones.

Not sure what you mean, event sound events pack work just fine for me

with no changes to my own loadlist, and having updated dbm, I've been getting this error.

That's DEFINATELY a Lua error within your addons code, not ours.

Unless you can link a source code, not much I can do to provide help.
