Oh this gets better.
Thanks for the reply Jason.
I've just logged in and changed the password as you suggested (that's ok) but I've tried unsuccessfully to change my address but it keeps coming back with the address unchanged.
Our address is a bit strange because the lane the house is on has no name, so the address is a house number and the village name so to try to identify the house better we have given the house a name.
I appears the updater will only accept an address it finds in its UK lookup table so we are stuck with the old address which because of an historical typo is different to the address on the house deeds.
At least our local postman (sorry person) knows us by name now and is very reliable.
I am still bemused by the fact that I can set up a subscription without having a valid Mytimemedia account.
Regards – Chris.
