Woops! That was Cobian 11 not 12. I will upgrade to 12 before more troublshooting. I have four other machines doing the same thing perfectly and I bet I have them on 12.
After upgrading to 12 and a good reboot, I can no longer reproduce any of these errors.
I did have to exclude C:\Users\xxxx\Documents\Wondershare, as the weird files structure freaked out Reflector. I asked the customer about is and he is fine with it as he is not using Wondershare any more.
Here is one of the Wondeshare errors:
