Server Down

Hi.
I maked my server with client by signe.
Everything was ok, but, after few days, I restarted the server, and now, when I try to connect to it, appear : Failed to connect the server.
Why ?
I think it's a login bug, but I don't know how to repair this.
Help me, please :(

try to execute
in Putty (or VM) if your main hard disk is full, you should delete your syserr files and clear the log table!

If this isn't the problem, please post your syserr

Same problem.
I don't deleted my syserror files, I want to give it to you to read them and after to say me what to do with them
Look : [Only registered and activated users can see links. Click Here To Register...]

SYSERR: Mar 30 00:14:51 :: ReadCommonDropItemFile: No such an item (name: µµ+1)
SYSERR: Mar 30 00:14:51 :: Boot: cannot load CommonDropItem: locale/germany/common_drop_item.txt

Thats the Problem
you changed the name of sword+1 (in this error) from µµ+1 to an other! But the Common_drop_item.txt calls the Item with this name -> can't find -> shut down the core

so, at the moment, if you start a core, it closes itselfe after booting!

How to fix:
1. Delete all enties in your drop files where the game can't find the item
2. You correct the wrong entries
3. You undo your changes in the database ;)

change you db

Same Problem : Failed to connect the server.

Another ideas ? Please ?
