Thread got locked while I was trying to post this initially...
Keni, man. Why don't you just start using 8.5 again? I know it sucks being out the cash and you want to use it so you don't feel it was a waste but dude... it isn't worth the level of stress it seems to be causing you. I was getting into that mindset a while back too but didn't have any other solutions in my toolkit so I was merely going to shift over to another DAW (the really inexpensive but supposedly rock solid one that shall remain nameless).
If 8.5 works for you it's better to just use that, create and be happy (or as happy as possible) than eat yourself alive over something that you simply do not like.
And I hope you haven't viewed my posts in the past as some kind of smug knowitallism. I truly wanted to see you get what you needed out of it. If that is not possible then junk the bugger.
Stay safe and sane, dude. I know that feel, bro. I know that feel.
