A major problem with my server.

Hello there.

First off I was impressed how nicely your system works, now I am pissed off. Like your service made me mad. Me and my friend play FTB Unleashed, everything was fine. Today we start up our server, and guess what?! WE LOST ALL THE WORK we did in the past 3 days!! No, I didnt use my restore backup, it just went away. I would really like that you inspect this and hopefully fix it. I cant use the restore button either because it's 3 days old.... That is about the same....

Good bye.

Well.... Still it won't help because It's limited to 50 MB... We were well over that

EDIT : Is there apsolutely no way to get it back?....
