How to install NZBGET?

well it still doesn't work unfortunately.
I first thought that the unpak file could not be found.
If i however change the filename in the config file to something that doesn't exist it errors and tels me it cannot find the file.
If i set it back to the propervalue it just tells me it can't start it.
So i thought it had to be accessrights.

At first i had used win7 and set everybody and root etc. to full-controll.
Then i used the chmod 777 bit in ssh.
Then i used setacl to add the user nobody and the group nogroup to the unpak.sh script file with rwx rights.

This still gives me the same error.
I still think it has something to do with accesrights but am stumped at this point.
I cannot ftp in there as root although i used the EnableSSH package.
So i can not see all the files and poke around in the nzb folder.
I am also no Linux expert but willing to learn.

Can somebody please help me here ?
Is there some log somewhere that perhaps details better what is going on ?
