If you have problem with gameguard, need to edit the "hosts" file which is found in the folder "C:\WINDOWS\system32\drivers\etc" and you must add in the last line the following commands:
216.107.250.194 nprotect.lineage2.com
Once you have saved the file, run the game by double click on the file "L2.exe" which is found in the folder "System" of your Lineage client.
