Hello Adventurers, We have been closely monitoring the situation regarding the issue of private servers providing unauthorised access to Black Desert Online. Our efforts include shutting these servers down by reporting cases of private server operations and taking necessary legal actions. What is a Private Server? Private servers are game servers or the means of providing game services that have been created by modifying and distributing our client without express approval, agreement or licensing from the developers of the game, or the publishers of the game for the purpose of providing illegal game services. We consider the operation of private servers to be an infringement of our copyright and we will be taking measures to protect our interests and the interests of the Black Desert Online community. As the use of unwarranted private servers damages the gaming experience of all of the adventurers who enjoy Black Desert Online through the approved channels. In a continued effort to shut down private servers, we plan to implement a Client Authentication System in Black Desert Online starting on November 7, 2018. We would like to assure our adventurers that the implementation of the Client Authentication System will not affect gameplay for those who access our game through the approved channels. Users may, however, experience an issue in which the client will not properly authenticate if OS time settings were forcibly changed on their PC, resulting in certain restrictions to gameplay. In the event that this happens, please carefully read through the pop-up alert from the launcher and follow the instructions provided to run the game. Synchronize the system clock on your PC to the current time and restart your game client. Right-click on the date and time in the bottom right of your computer screen. Click on "Adjust date/time" Make sure the following 2 options are turned on: Restart your computer After this, you should be able to start the game again; If this still does not work, try the following: Open your Control Panel by writing "Control Panel" in your Windows Search bar: Open the Date & Time settings On the "Internet Time" tab, press "Change Settings" Make sure the "Synchronize with an Internet time server" checkbox is ticked and then press "Update now" Restart your computer Please be mindful that game play may be restricted if our system detects instances where the same actions are repeated multiple times. If you are unable to start the game due to client authentication failure, please contact customer service for assistance. We would like to assure you that we are committed to maintaining a user-friendly community. If you find any private servers, please be sure to submit a report regarding this to the Game Master Team. Also, please note that gameplay restrictions may be enforced against users who promote or advertise private servers. We would like to thank you for your unwavering support. Update 14:50 UTC We have located an issue where some players' Launcher is not being updated, preventing the game from authenticating properly.
