Have just discovered that, 'nearly' all my expansion kits are loading and working in the new BFDLAC format so if you have any expansions that you converted to the new format you can point Eco to them and see if it picks them up.
Unfortunately all my the kits in BFD3 format but all the individual kit pieces load in BFD in Eco now.
But it seems the 3rd party ones don't, so can't load the BFD3 kit pieces as they were recorded by Platinum Samples.
Actually, the Chocolate Audio Imperial kits pieces are loading so some 3rd party kits do load.
I would actually have to load the kit pieces and save them in the Eco format to load full kits.
Still, if you have other fxpansion kits you can just point Eco to them and if it doesn't like them it will tell you so ;-)
