Solved not writing to YAML Config?

Ok so I have this code, but every time its ran the config stays with 0 bytes of data, but no exceptions are called.

Code (Java):

        if (!(Main.q.contains(p.getUniqueId() + ".currency"))) { // Not sure if this is the correct if statement to use.
            p.sendMessage("Working | " + p.getUniqueId().toString()); // User gets this message
            Main.q.createSection(p.getUniqueId().toString());
            Main.q.set(p.getUniqueId().toString() + ".currency", 0);                        
        }
       

- The UUID.toString() does not return null, tested and confirmed.
- The file path is correct, tested and confirmed.

Main.q :

Code (Java):

public static FileConfiguration q;

...

File fl = new File(Bukkit.getServer().getPluginManager().getPlugin("Shen").getDataFolder(), File.separator + "Shen.yml");
        if (!(fl.exists())) {
            try {
                fl.createNewFile(); // This works
            }
            catch (IOException e) {
                e.printStackTrace();
            }
        }
        q = YamlConfiguration.loadConfiguration(fl);

Thanks in advance, not sure what im doing wrong here :\
