Hello pobrienjhu,

There are no other hints I can think of except that when you retrieve the MIDI file via email, the file is added to the database that stores Treo 600 ringtones. This database file is called "MIDI Ring Tones 1.0" on your Treo 600; it is a hidden file, so you won't see it unless you use a file utility like Filez to view it. You might check to see if the ringtones are indeed there.

The only other possibility I know of ideals with the size of the midi file. You can read about this in the palmOne Knowledge Library article "MIDI file won't play (Treo 600)".

Sincerely
Kevin
