IPS Definitions Failing to complete

Ever since updating to version 22.8.0.50 on 27th September, first run of Live Update each day returns a 'Failed To Complete' in History, picks up on second run of Live Update of the day. First failure is for best part of 300-500 kb, successful download 4 MB. Same on both computers - anyone else noticed ? Prior to this used to get the 300-500 kb once a week - 3rd Oct will be 7 days from working OK (updated 22.8 pm on 27th) - worked OK that morning prior to update. Any one else noticed?
