Motorola V551 / V330 / V547 / V555 / V557

Ok...heres the thing (i'm a sony ericsson dude, just had a problem with my Z500, great phone btw). i downloaded the drivers and P2kman and transfered mp3 tones i shortened and optimized for ring tone use. they went into the file manager or whatever and plays. but it doesnt show up in the audio settings menu. if i choose to use it as a ringtone from the file manager, and if the phone rings, theres no sound. if i try to get into the ringer profile settings, it doesn't want to go. it just goes back to the main settings menu.
