News Feed Error

[nook77]

I keep getting the following error:

IOError: [Errno 13] Permission denied: 'c:\\user'

I do not get this all the time - the recipe works fine, then the next time I fetch news. the feed download will stop around 67% and fail. It seems to me that it's a problem on my end and not the feed source, but I can't figure it out. I appreciate any help/suggestions.

UPDATE:

This is the last part of the status codes each time this happens:
