Nokia :: 5230 - Unable To Access Ovi Maps

I have recently bought a 5230 with Ovi maps supposedly installed and since re-installed several times. It has proved impossible to access the maps and despite e.mails and phone calls to Nokia, Carphone Warehouse, and Talk Mobile, no one is able to resolve this problem, or reply to e.mails.I have also spent nearly four hours, in two visits to a branch of Carphone Warehouse, and despite the best efforts of the staff, no one can come up with a solution. Every time I try to connect, I receive " connection failed, please try later," no maps, nothing but empty screens.It would appear that it is impossible for this phone to achieve "what it says on the box."
