I have a problem. My game was normally working but today I installed an antivirus and it found a trojan in Play_L2Classic.club_2.0.exe file and deleted it automatically. I deleted all the files, and downloaded them again. I turned off the antivirus, and I copied patcher and updater files into the un-zipped client folder, I checked files, clicked the START button and... nothing happened. Just an icon of l2 process appeared for a few seconds on task manager and that's all. I'm confused because today's morning it was working fine.
