Hi Allgood,
If you haven't found a solution yet. You are not the only one to have done this, we used Streatham PC Services, John Kazantzis: 07962 058553, to retrieve information we'd lost, when we had a similar accident.
Learning from our mistake we used JMS Secure data to set up a retrieval process to make sure that everything we do is and has been backed up since, Marlon Johnson: 020 3397 9026 / 020 3397 3378,
