Catalex MP3 Playing: 0

Im new to arduino and i just bought the mp3 chip. I used the sample code ArduinoSerialMP3Player/ArduinoSerialMP3Player.ino at master · cefaloide/ArduinoSerialMP3Player · GitHub and so far i can't get it to play any music. No matter what command i give it the response will be Playing: 0. The card is formatted FAT32 and the folders and songs are named like they should be.

Any ideas on why its not working?

I checked the code on my Catalex board and it works fine.

After upload to an Arduino Nano and open the serial monitor I get
Sending: 0X7e 0Xff 0X06 0X09 0X0Sending: 0X7e 0Xff 0X06 0X09 0X01 0X00 0X02 0Xef

After sending a 'p'

Play

Try to copy the mp3 files and directories that there are in the repository

I think the problem could be in the SD Card files.
