Sure Signal V3 won't register

[sweet_lfa]

A friend has given me their Sure Signal V3 which is in working order.  For some reason I can't register it and keep getting the following error message:

Sorry – there seems to be a problem.

We're working hard to fix the issue, so please try again later.: 500, 1013

Please can someone help me?!

Hi there, 

Your friend would have to de-register it from his account for you to be able to use it. He would also need to change the address as well.

Hope this helps.

Thank you. I will find out if it has been de-registered and try again.
