Cannot read model error

Hi,
I’ve downloaded, installed and configured sub-zero as per the wiki. It seems to do an ok job at finding existing subtitle files, but it doesn’t seem to be downloading anything from addic7ed.
As far as I can tell, it’s throwing a bunch of “Cannot read model” errors, but I can’t find how to solve them in this thread.
Here’s a copy of my log as of 5 minutes ago, if that helps. Thanks!
Paul
