How can one get Sony DPT-S1 repaired

Hello!

I bought a Sony DPT-S1 a few months ago. Overall, I love the device, but I recently broke the clip on the device that holds the stylus. Does anyone know where I can purchase another one of these? (The clip I'm talking about simply snaps onto the device.)

I also am having an issue with my device suddenly crashing on a (very frequent) basis. Does anyone know where I can send off the DPT-S1 for repairs here in the states?

Thanks
