Hi everyone,
If your Lineage II game client crash for any reasons, there is a possibility that you may be prompted with an over-sized login screen on the subsequent sign in. If this does happen, simply click on the EXIT button. Browse to the location where you installed your Lineage II game client, for example C:\Program files\Lineage II\system. Under the System folder, there is a file called OPTION.INI that store all your in-game resolution, color depth, audio settings, etc. Please delete this file, OPTION.INI and relaunch your game client and your screen resolution will be reset to the game client default of 800x600.
You may reset the option once you have successfully sign back into the game world.
Enjoy!!
