I added the poundbot and did the api key etc and it showed that my steam id was succesfully registered yet there isn't any PIN code being sent.

I also get this when I reload the plugin:

(14:54:51) | Web request produced exception (Url: https://api.poundbot.com/api/players/registered) in 'PoundBot v2.0.0' plugin (NullReferenceException: Object reference not set to an instance of an object)

Ok I figured out that it is working for new people just not me (the server owner). It probably saved me already in a database somewhere on an old server maybe or I dont know but how do I remove data from this so I am not registered anymore and can re-register myself? Where is the data stored?
