It is probably not related to the problem, but a strange coincidence. The actual file showing bad is CNBJ2530.DPB. And the file may not be bad, just the database used to check it.
I have tried to see if I could replicate the situation with another Win 8.1 machine, but have not yet seen it on that one.
It may be related to some update for Windows 8, there have been some large ones lately.
But uninstalling and reinstalling is a good idea, as Digerati suggests. Other things come to mind if reinstalling does not work, and those would be anti-virus utilities and Firewalls.
And I may have the wrong error definition (0x00000002), but it might be a "File not found" type of message.
