For myself, i find no solution.
But when you can connect to Filezilla, do a backup from your Server.
This means all shops an much else what you want to save.
Then make your Server new.
After that you can reload the Backup from your server.
It is maybe a time from 10 to 15 minutes.
You can try it, but not on my responsibility

Or try to change your keyword in filezilla first.
You have got the daroo files?
Then try the keyword in filezilla: "daroo" (Without"")
I wish you good luck.
And sorry for my english :P
Sincerely yours Phil
