Have you tried to rewire it in Reaper? When Broomstick stopped working for me I had at least a year of utilization by rewiring Reaper in Cubase and loading Broomstick in Reaper. It may be that some other DAW is also capable of running Broomstick that you can rewire in CB8.5. Many have a free trial period. Reaper is very cheap and solved the problem for me for a while. However and sadly not anymore so I have the mentioned two computer solution with CB 4.5 on the old PC and 8.5 on the newer MAC.
