Hello, dear user,
1) Please make sure you've downloaded the Gracia Final x7 game client exactly from our portal, and that you haven't installed any third-party modifications (f.e. patches) - E-Global - worldwide Lineage 2 project. Off-like sources - Interlude, Gracia Final, High Five, Classic.
2) The most common cause of damage to any game file is antivirus and/or firewall, so to avoid this in the future, please set the game folder to the exclusion of all defenders.
3) Then you need to update your game files via full chek using our updater GraciaFinal_x7.exe (it's located in the root folder or the game client). To make full check correctly you need to:
- delete "System" and "Systextures" folders from your game client;
- Run the updater "GraciaFinal_x7.exe", click "Check files" and wait for the full update of the game files.
Please let us know if this helps.
