can’t seem to get passed waiting audio engine in dorico 4 win 10. have restarted computer, turned it off for a while then back on. nothing. It worked fine up to now. suggestions?
Initially, it spends quite some time scanning your plugins… How patient were you? 
20 minutes. A message on the forum suggested reloading 3.5, running it, closing it and starting 4. It worked and has continued to work.
All is well.
