@BigFriendlyDrums If it’s any help, I don’t have BFD2 either, but some of the packs seem to be using BFD2 structures which BFD still supports. But I am using Windows.
I raised a support case at the time, which could be your best bet. They took a couple of days to respond (by which time I’d had success with the above approach), but they did get back to me.
