Using via DMB movie boards and says my key is now invalid.

I don't see any problems with TMDb.
See here https://status.themoviedb.org/

Only the Travis Bell admin and you can access your API Key.
So I suggest you

Take a Test
Using a computer, desktop or notebook.
On some mobile devices this test may not work correctly.
In the URL below, change THE_KEY to your API Key.
https://api.themoviedb.org/3/movie/550?api_key=THE_KEY
Use this example to do a search using a new tab or window in your browser.
You will receive the basic data of the Movie Fight Club (1999)
https://www.themoviedb.org/movie/550-fight-club
If it works, your Key is OK.

When there is a problem, the TMDb Server sends a message.
Can you tell which message the server sent?
Here is a list of possible messages:

If this test works or if it doesn't work, please let us know here.
