Exactly! You are trying to use a database from 0.3.6, that is the problem... For TFS 1.0 the fields are individual for each skill and NOT nested within player_skills. You really should look at the schema.sql from TFS 1.x, that is where you will see the database structure, but you are trying to use an old database, you would be better off just making a new database, otherwise you will probably experience issues all the way through.....
