0.6.18 Download Error

[Spankypoo]

Just upgraded to 0.6.18, and this is the error I get when I try to download The Economist.

ERROR: Conversion Error: <b>Failed</b>: Fetch news from The Economist

Other weirdness: scheduled the WSJ, and under Scheduled I just saw another publication. Not the WSJ.

And now when I try to search for publications, I get:

ERROR: ERROR: Unhandled exception: <b>AttributeError</b>:'NoneType' object has no attribute 'showing_count'

Traceback (most recent call last):
  File "site-packages\calibre\gui2\dialogs\scheduler.py", line 61, in search_done
AttributeError: 'NoneType' object has no attribute 'showing_count'

I tried uninstalling it completely, making sure there wasn't anything left in Program Files, reinstalled -- still broken.

Any ideas?

Edit: Running Windows 7 64 7100.
Edit 2: It fetches Slashdot just fine. Having looked at economist.com, I'm guessing it's breaking because the content's now locked down...? And rebooting fixed the search issue. Weird.
