1. When was your last backup?
[nothing will be lost, it's all still there]
2. Save your $50 and contact your host support, that's what they are there for.
3. Backup...backup...backup [you should really have a backup plug installed, but if all else fails, your hosting should do automatic backups of all your files]
If you still need help, I can. I wont take your $50 unless you want me to, then is a lesson learnt the hard way.
