Looks like the technical side of this is getting taken care of by support, and they should be with you shortly on that end of things. However, I do think this might be a good reminder for all to remember to keep backups of your web sites. We provide a number of different ways for you to backup your content, you can get more advice on this here:
http://wiki.lunarpages.com/BackupsWhen a backup restore situation comes up, it is important to contact the support team as soon as possible, to make sure that a backup can be recovered. Due to storage concerns, because we don't want to overload our customers' servers and hosting space, we limit the number of backups that are kept.
If you ever any any questions on what might be the best way to backup your content in the future, feel free to ask here. We have many helpful members here that would be more than happy to assist you. Thank you for your time!
