Plex account is missing the server token

[ichibansenshi]

I get this error message. I installed kitana multiple times, and also deletet the mounted folder from /app/data but no success.
Even if i delete everything, it has still the Settings from Last time (trakt pin and so on) and i think that is the problem.
How do i completely delete all the files?

Edit: found the solution. here for everyone that runs into the same issue the guide

trakt/Plex-Trakt-Scrobbler#611

Option2 worked for me.
