Player Files Not Working

I'm trying to create player files on join using this file, but it won't create it:
error: http://gyazo.com/9a9d2c52280769a566d31647950fc328

Code:

package me.crazymanjr.shotcadehub;

import java.io.File;
import java.io.IOException;
import java.util.UUID;

import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.configuration.file.YamlConfiguration;

public class PlayerFile {

private UUID uuid = null;

private File file;
private FileConfiguration conf;

public PlayerFile(UUID uuid) {
  this.uuid = uuid;
}

public void load() {
  if (file == null) {
   file = new File(Main.get().getDataFolder() + File.separator + "playerInfo", uuid + ".yml");
   try {
    file.createNewFile();
} catch (IOException e) {
    e.printStackTrace();
}
  }

  conf = YamlConfiguration.loadConfiguration(file);
}

public FileConfiguration getConfig() {
  if (conf == null) {
   load();
  }

  return conf;
}

public void save() {
      if (file == null || conf == null) {
       load();
       return;
      }

      try {
       getConfig().save(file);
      } catch (IOException ex) {
       Main.get().getLogger().severe("Unable to save " + uuid + ".yml.");
       ex.printStackTrace();
      }
     }
}

 

Instead of saying "playerInfo", uuid + ".yml", why wouldn't you just do "playerInfo" + File.separator+uuid+".yml" in the first place?

The server could not find the location of your player file! You might want to check if the location of the file is correct (Line 23).
