[knives of ice]

I can add artwork with Artwork Beef for individual movies or tv shows that is not a problem.  However, if i try to run it in mass or new videos or any/all videos I get an error telling me to check the log each time.

Any idea where this log is located?  I checked the log folder, user data, addons but can't locate it anywhere.  Not sure what the problem is and why things keep erroring now.
