Well I'm still running Komplete 8 never saw a need to go to 9 but the NI stuff doesn't cause me any issues.

I would say if you are willing to still give it a go take one of your machines and dedicate it to pinpointing your issue.

Clean OS install with nothing but Akai and then add things individually and test.

May seem like a lot or something you shouldn't have to do but it could help resolve your headaches.
