Audio driver issues between Platinum and Mixbus!

PLEASE! Somebody must know of some settings I can start looking at. I have suspicions that it is a Windows setting that I just haven't known about. As long as I use Platinum everything is great. If I try to use any other DAW I lose my drivers in Platinum! Surely someone can help me with this.

Platinum is my #1 DAW and always will be! I just like to master and do live recording in Mixbus. I agree I have never had so much trouble with the Studio-Captures and Sonar and Mixbus getting along. It has to be the crappy Roland drivers! I am running the same audio programs on a Toshiba laptop with a very old Focusrite Saffire interface and have absolutely no problems whatsoever. I am talking now with Harrison about how to figure this out and they are being very helpful. The early versions of Mixbus never gave me any problems but since Mixbus 3 first came out it seems it started.
Anyway, thanks, John. You have been a great deal of help for a while around here.

I fully trust Mixbus 3.2, Studio One 3.2, Reaper 5.x and SONAR since they all work perfectly with my RME UFX in ASIO mode even if I change buffer size between DAW usage under Win10 64bit.
 
Mixbus 3.2 is at it's most stable for me right now.

IS it perhaps the use of two linked interfaces that's causing the problem?
My Steinberg has no trouble bouncing between programs, although my Quad Capture used to. I use my audio interface for all windows audio.
I have the "share audio drivers" option unchecked in my preferences. 

Thanks, Bapu but I have tried that and still no love. Ampfixer, that has crossed my mind but when I use just mixbus it gives me all 32 ins and 20 outs for live recording. Everything works fine until I go back to Sonar. Drivers are gone.

I imagine that will work since DirectSound and mme work but the latency is horrible as far as using that WDM driver for anything! As I said, I use ASIO because I can get my latency down to 2.1 ms. The other drivers are 15 and up ms. I can't work with those kind of latencys. Mixbus and Sonar get along great on the laptop so I guess I will use it there for mixing and mastering. That Saffire 6 USB only has 2 ins and 4 outs. No live recording there!  I have never tried using the Roland Studios on that laptop. I guess I will have to bite the bullet and try them on the laptop to see if I have the same issues. It can't be anymore trouble than I have now. Famous last words, huh? LOL
Harrison did contact me back and I have to say Ben over there has given me one of the best support experiences I have had in a long time! He makes you feel as if they really care about your problem and they SINCERELY wish to make their product the best they can. Even if it is in small baby steps. Anyway, we emailed back and forth a few times and he said they had even tested on a Octa-Capture which I don't think is much different from the Studio models. Anyway, he has not seen any issues so far. I asked him if they had tested between Sonar and Mixbus with the Octa-Capture and my response was that I had exceeded their abilities to troubleshoot with my own troubleshooting but they would still keep working on the problem. We will stay in touch. Hats off to Harrison support.
I didn't mean to get long winded but as I posted I would let you all know if I happen to stumble on the magic combination. It has to be a setting in either the programs or a Windows 10 setting somewhere. They all worked fine for a long time and then about the time windows 10 came out even before I installed 10 everything went haywire.
Keep you posted. Thanks, guys.
