1. Download the game and do NOT UPDATE IT!
2. Get the ini of a server and place it to your lineage2 system folder
3. Run the Game FROM the L2.exe of your lineage2 system folder.
4. Enter a login and a pass, it create your account automatically.
5. You are in the game.
hmmm.... try clicking the shortcut in the main folder first, if its a fresh install it might only run if you've run the autopatcher once (if you have the american client, just let the patcher finish).
