„AAE -9173 error“ - the biggest pro tools workflow killer over the last years

[monet]

I'm still getting it w/nothing on the masterbuss but things on regular tracks...I'm unclear...is everyone else past this? because I couldn't even get 2018.4 to launch...went back to .3 (came from 12.x)...still constant 9173...1 audio track and 3 midi tracks...the error comes up when the 3 midi tracks come in...am I so clueless that everyone else has fixed this? avid to me to freeze track it...1 audio track and 3 midi tracks....kontakt may be the biggest problem but am I not supposed to use it? how does it work for other people but not me??
