Can't cd via ssh script - Debian

I have one Debian 6 Server where it doenst work to run a cd commond through a ssh script. It allways throws the error "cd: can´t cd to /home/user/directory/ \ Error: Unable to access jarfile name.jar"

I douple checked the permissions. They look all fine.

755 on every folder
644 on the script and jarfile
home directory´s ownership is root:root
subfolders and files ownership owns the user which runs the scripts (user:user)

The thing I dont understand is, that it works on my other three servers just fine and the setup is the same.

#!/bin/bash

cd /home/mcgameserver/unhinged/
java -Xmx30M -Xms30M -XX:MaxPermSize=40M -jar Minecraft_RKit.jar

this also doesnt work:

DIRECTORY=$(cd "`dirname "$0"`" && pwd)
(cd "$DIRECTORY"; java -Xmx30M -Xms30M -XX:MaxPermSize=40M -jar Minecraft_RKit.jar ${USER}:${PASS})

The same script is running on 3 other servers. They are all installed the same way by me.

Solution

If WinSCP is in text or auto transfer mode the End-of-line characters setting in the Environment dialog might have kicked in, possibly altering your linebreaks.
