I have confirmed with a fellow RME user that the current drivers are doing some funny stuff in Windows 10 Pro x 64, such as simply disappearing requiring a quick re-install. Anyone else able to corroborate this? I emailed RME a while back but they of course claimed it "wasn't an issue on their side.."

I have the latest drivers and an original Babyface, and I've had zero problems. Rock solid and stable. Been using these drivers since beginning of July....FWIW

Hi. I have not had this issue with my RME Ucx in Win 10 Pro X64.
All the best.

No issues.
