First my specs: 
	Computer: Windows 7 Home Premium SP1 
	DAW: Sonar Platinum 22.10.0 BUILD 19 [2016.10] – x64 
	Sound Card: Roland Octa-Capture 
	Midi Interface: MOTU Micro Lite
 
	I have seamlessly been using 8Dio /Kontakt-based libraries  for some time. That is until I went to open Sonar Platinum and I got this message:  There are no audio devices for the current driver model on your system. Please go to Edit / Preferences / Audio / Playback and Recording and choose a different driver model.
 
	Thing is after that message, Sonar wouldn't open. I tried re-booting... nothing. Then I updated Sonar and still it gave this same message  and wouldn't open.  Suddenly it opened (why??) and I immediately tried to look at the  Preferences and check the audio settings. Under Devices there were none listed! After some research, I tried changing to  MME (32 bit) and the Octa-Capture audio device   reappeared. So far so good, until I tried to play my Kontakt based instruments and the latency was about a full second between pressing the key and the sound. The midi recording of those same instruments  played back fine, EXCEPT out of sync with the DAW. 
 
	Tried changing the latency and the midi buffer, but nothing addressed that. I'm at my wits end as this problem came on so suddenly and, of course, I'm in the midst of a big scoring project. 
 
	Help? Thanks  in advance.
