Problems with thetvdb and fetching metadata

Hi,

Recently I have had some trouble with metadata not downloading and shows not being matched. Nothing has changed when the issue started to occur, but I did try install the latest PMS to see if that would fix it.

Here is a log from the thetvdb agent: http://pastebin.com/0dt9n4HS

Not really sure where to start looking at the cause of the issue.

Any help would be much appreciated.
