FWIW I had an issue on Mac (PC was just fine) with the new BFD3. Support was useless, they might have asked me "Did you try turning off and turning back on again). However a BFD3 forum user gave me the solution so it worked a treat.
I don't think under InMusic BFD3 is mature yet, so for now I'm shying away from it until I hear that BFD4 is on the horizon.
