Freeroam V2 - Not really working

Hello Guys, i have a Problem with the Freeroam V2 Gamemode.

I installed all files and fixed the location in one file, and installed mysql and imported everything and edited the login info in the config. now i start the server and get this weird error:

Ingame /register wont work and serverconsole gets spammed

What should i do?
