Mp3Trigger Can't Upload Arduino

Hi there, I was trying to upload a program for the Mp3Trigger, but alas, I’m getting this error. Can you explain to me what has gone wrong? I’ve update the latest firmware and included the Mp3Trigger in my libraries both in Arduino app and in my documents.

heres’s the error message;

In file included from Mp3Trigger_Piezo.cpp:1:

any help?

thanks in advance

Are you on at least Arduino 1.0?

i’ve tried different version of arduino. from arduino 21 to version 1.0.

i’ve updated to version 1.01 and this is what i get as error,

Mp3Trigger_Piezo.cpp.o: In function `setup’:

Mp3Trigger_Piezo.cpp:16: undefined reference to `MP3Trigger::setup()’

what could be the problem here?
