Restarting problem?

Hello,
When I want to start my Terraria server, it keeps saying that I didn't close the server in the correct way. It also keeps spamming my console with
"Server Restarting....

Tshock was improperly shut down. Please avoid this in the future, world corruption may result from this."
My logs say the following;

2012-06-27 18:38:47 - TShock: INFO: TShock was improperly shut down. Please avoid this in the future, world corruption may result from this.
2012-06-27 18:38:47 - TShock: ERROR: Fatal Startup Exception

EDIT: I even can't type anything, it just spams me with:
"Server Restarting....

Tshock was improperly shut down. Please avoid this in the future, world corruption may result from this."

So, Is there a solution how to fix this without losing a world, and how to properly shut down the server?
Because when I do /off it only restarts, and I don't see any further commands to stop the server.
Please help me.

Well, typing in "exit" (without the quotes) in the console or /off in game are two of the proper ways to shutdown your server.
To fix the issue, I would grab a fresh copy of TShock. The world should be fine, the worlds aren't stored in the TShock folder, they're in C:\Users\USERNAME\Documents\my games\Terraria\Worlds.

Thanks for the help, but the /off command restarted the server for me , but exit helped. (tryed it before and didn't work, probably a typo.)
And my world is now corrupted... I can access it from another server without TShock and with, but it will show a black screen, and the server will just boot me and others.
Any ways how I can de-corrupt my world, or is it just basically gone?

Can you access it on single player? (Try it =P)
If you can, try it again with the server. If you can't, check out TEdit, see if it can open the world file.

I did not "fiddle" with things. I never even knew that there was that config file. I couldn't open it with either Notepad, or Eclipse. I may have a old version of Eclipse, but I never opened it.

I'm sorry, I was a bit annoyed when my world got corrupted. I shouldn't be mad at you nor Tshock, it was actually my own stupid fault. And thanks for the information, I will test it right now and see if it works.
