re :Having same problems with TB on wife's computer........error failure for policy reasons

This sounds like BT is blocking the IP address. I've known it to occur if you were travelling, so using different isp access or if suspected spamming activity.

On wife's computer and on your computer are you able to logon to respective BT accounts using webmail via a browser ? Please do this on both computers and report back with results.
