Motorola V635

This is really annoying me, only just got the money to buy the phone and now, two days later, its playing up. Grr.

Basically...

I can succesfully send pictures to and from my phone BUT:
When I send an mp3 (using MPTools and yes it is updated!) it will succesfully tranfer to the flash card.

BUT

when I try to send an mp3 to the phone itself (so I can use it as a ringtone) it says it is transferring but it does not appear on the phone

The phone was succesfully letting me transfer files directly to the phone itself but now it is not.

The phone does have memory free, and the ringtones are short 10 second .mp3s and are under 20kb

Ok, so another method:
Once I have sent the file to the flash card I go to menu>sounds...
