That's why i said if it's an active project . You don't know on what this pack is working.
Failed.
Well , if you have a compiled pack do what i will say below :
Backup your custom scripts and data, overwrite the .jar files and data folder if needed, check if there were updates on DB, update your tables, or remove them and implement the new sql files.
ALWAYS be aware of having backups of your custom information and your working DB.
If you have preconfigured pack , you can't.
