For me this issue had nothing to do with Kontakt. But perhaps this helps.
Possible solution (assumption):
Win 7 Professional
RME Fireface 800
PT 9.0.0
I had the same problem after working a while with projects in 192 kHz.
When I tried to open an older session in 48 kHz I got these errors on opening every session and backup. Scary!
I noticed that PT switches automaticly to my MBOX 2 driver and my Fireface switches automaticly to 192 kHz while opening a session.
My solution:
- set the samplerate again to the sessions setting manualy
- set the buffer size to the value with which you saved the session
or in my case 512 samples
- switch drivers in PT to Fireface (or your device)
I hope that helps!
@ Avid:
This was the worst error i had so far.
Please work on these things.
We all paid a lot of money.
Such a mayor error one day before deadline is no fun at all!!!!
