Hello,
I have now fixed TMDb provider due to their release of new Api and discontinued the old Api. New version is 1.1.
To get the new version launch TViXiE (must be version 1.3.2 or newer) and do the following:
* Click Tools->Update Manager
* Click "Check for updates..." button
* Check the "Show only newer or updatable" checkbox
* Select the TMDb provider in the list
* Click the "Update" button within the TMDb provider selection.
* Restart TViXiE and you're done.
Regards
Mathias
