Thanks Dwardzala, Chuck and 11Dreams.
I reauthorized my computer and AD works now.
I've found that my audio dropout issue occurs during looping an 8 bar section while the in console view. The session I'm working on has 117 tracks works fine in track view.
Maybe it's a bug they can work out on the next update.
I also had to rescan all my VST3 plugs due to them not showing up in the FX bin initially.
It works fine now as long as I don't loop. But I need loop.
Thanks again guys for your expertise.
Mark.
