Hi, I've been trying to register a Sure Signal vers 3 on the Vodafone website but it continually displays an error after entering my details. "Sorry – there seems to be a problem. We're working hard to fix the issue, so please try again later.: 500, 1013" I've tried using different browsers and clearing my cache but without any luck. I bought the device second hand and I was wondering if it could still be registered to another account. My Sure Signal serial number is 40124242047 Thanks
