Avast Error message 102 After restoring mobile settings

I am not able to restore SMS, contacts etc that I have backed up after my mobile phone was reset to manufacturer settings. Unfortunately I installed avast again on my phone so now it seems I have two accounts for same mobile. When I log in to the old account I can see messages, contacts, etc but I can not restore them back to my phone - as I get the error message 102. Does anyone know how to fix this?
