Excellent advice and most likely the cause of your problems has already been given so I will only add this:
To determine if your unit is defective try recording sometime at 96K and 192K; something like a guitar, bass, vocal, etc. Do not use BiaB in this test. If you have no problems then your unit is not defective.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
