It appears that the hosting company had a major hardware failure earlier in the week and the backups where not working correctly. I need to apologise to all users that have signed up or posted since the 1st Feb 2011 as that is the latest backup they seem to have of the system.
For those who have e-mailed me directly, all I can do is apologize now. I will be doing a full backup of the sites database each week from now on as I do not want to loose the database again.
