Well! I made the jump this morning to Windows 10. The Windows 7 computer had NO issues whatsoever. And the 2 Studio-Captures lit right up and are working fine!
BUT! I installed 10 on my 8.1 laptop and all hell broke loose with the Studio-Captures! It seems the old driver was keeping the new drivers from seeing ANY Studio-Captures at all!!!!
The problem was finally remedied when I un-installed the old drivers. As soon as they were gone, everything went smooth as buttah. I don't know for sure but anyone using these interfaces might need to just un-install the old drivers before you upgrade to 10.
I know all systems are different but this was my experience this morning.
Anyway, all seems well now in 10land.
