Sharp GX20 - Sending music files to use as SMS alert?

[Rommel]

How do you send sound files to this phone to use as an SMS alert? I know how to send by the infa red port and the files are all the correct size that's not the problem, it's getting them to work once they've sent. I've done it before and got one on so it can be done but I lost the software I used to do it and don't know where I'm going wrong with the new software. I'm using the handset manager CD I got with the phone, it's says MIDI, WAV and MMF files are supported to do this but when I send a WAV file to the phone it just comes up "[File name] Illegal data." And won't play. The tune I sent and got on is listed on my phone as a SMAF file not WAV I don't know why either. Help.
