Allright the are some problems with the SQL Syntax if you use MySQL most people seem to have no problems if you use MariaDB ( https://mariadb.org/ ) .
If you use MySql after installing open Up MySQL Workbench and double click local instance. then Write CREATE DATABASE Darkflame and run it by pressing on the lighnting symbol.
​
Delete the text and write USE Darkflame.
​
After That copy and paste the SQL Code from the Repository but delete OR Replace from all lines. Also you need to delete " DEFAULT ''" from the Table creation called ugc filename line. Then run it
