After moving to a new address recordings do not play anymore

Accounts seem to be connected to an address, not a person. Thus your move causes the creation of a new account, and deletion of the old. Recordings are connected to an account - you cannot take them elsewhere. Unfortunately, this puts you in the same position as those who have had malfunctioning hard drives, or needed to upgrade equipment for other reasons; the recordings are lost.

With time, all recordings are ephemeral.
