You don't have local backups? I hate seeing people have to learn the hard way, but I guess this really nails it home. Have local backups. Don't ever not have them.
Also, this might be a good time to consider completely different IB software if you're going to start from scratch. Vichan and its forks are not really maintained. If you use vichan or forks and you need help or need something fixed, to my understanding you're entirely on your own to do it yourself. Probably a terrible choice for someone who is not a web dev.
