I'm trying to create some of my own ringtones for my NEC 525 phone. Currently the software that I'm using is Cheetah Audio Converter (to convert from MP3 to Wave), Audacity (to select what sections of the Wave file I want), Yahama SMAF (to convert to MMF), PSM Player (To play the MFF), and the NEC Memory Editor (To load it to the phone).

If first is seem that everything was working well, but now I get this message when trying to load the files to my phone, "All Rights Reserved. Cannot Select". This means that there is some type of copy protection on the MMF file, but I don't know where it came from. When I first started it let me put MMF files on the phone, which were from the same MP3.

Does anyone know what this could be, or can someone suggest the best FREE programs to use for this. Thanks.
