After trying multiple things to register I left the registering process open in my phone for some time (say 1 day give or take) when I retried the phone call option it worked. It might be related to their server problems or it might've worked because I sent em an email asking em to reset the process. Whichever way it worked. If you have issues registering try emailing them and then trying the call option, if it doesn't work leave it open on your n9 for a few hours then try again. Cheers!
