Sorry to see you are having issues. If you can send me your ticket number I can take a look to see if the reply somehow did not make it your way. Currently I am not seeing any active tickets that link to an Avorion server.
Depending on the mod pack we can try to get it installed for you on our end through a ticket. If it is just a mod then we can give access for you to upload the jar files.
Looking at the back end with your username it seems your server is up on your control panel as of now. You should be able to log in and see the server.
For this make sure you are making the edit in the right file. There are two serverDZ.cfg files with one in the root directory of the FTP client and then one within the admin folder.
Sadly the save data and server files are locked currently. As the developer has requested that the data remained locked till they are ready to release the files for full launch. Currently we do make backups on our end that can be restored from the panel.
