Server crash

[TwilightRaven]

Does anybody know what this server crash error means? I just added a lot of stuff and stupid me forgot to back it up. Anyway this is the message I get:

Error:
System.IO.EndOfStreamException: Unable to read beyond the end of the stream.
at System.IO.__Error.EndOfFile()

Corrupt save, you probably closed the server while it was saving
