Kodi V16 on Openelec 7.0.1 - TVDB scraper stopped working

I have had a problem for a few weeks where new TV shows would not get their details scraped etc etc.
I finally got round to checking what was going on .. it turns out that in the https api call to api.thetvdb.com I dont see the API key after Authorization=Bearer%20.

I know the versions are old, but they have been working flawlessly for ages now .. maybe it is time to update! But is there anything I can do to fix my current system?

Thanks

Steve
