Performance Task 1 fail error=401

[DakenDog]

I keep getting a Task 1 Fail! Error=401 message when attempting Blu-ray full disc copy to BD25. Discs copy fine for BD50 but will also fail when attempting to compress BD folder down to BD25. This occurs on versions 8.1.7.8 thru 10 running Windows 10 64-bit. Licenses are fine. Help!!!!

reinstalled 10.0.2.8 and making an attempt all seems fine at the moment but will post log if there are any problems. had been primarily working with version 9 when this issue suddenly began.
