Motorola V635 - Bluetooth problem

[Unregistered]

I have a problem that is really doing my head in now. My girlfriend has a Motorola V635 (http://www.cellup.com/MOTOROLA-phone-MOTV365-cellular-accessories-Manufacturer.html) and I'm trying to send her various pic or sound files via Bluetooth. My phone connects to hers fine. The motorola connects and then says 'incoming transfer'. The name of the file that I'm sending to her comes up on her screen and it asks me where to store the incoming file (Trans-sim or Phone). When I select either of these, it goes to the percentage transfered screen with a bar saying 0 - 100% complete but almost as soon as this screen flashes up it flashes off again and a message saying 'connection interrupted' appears. Please can anyone help before I launch her phone through the window. Also... how do I send messages via bluetooth from her phone to mine. When I open a picture on the her phone I can't find any option to send via Bluetooth.
