Run Game Advisor.
To download the Game Advisor, go here: http://us.ncsoft.com/gameadvisor
When prompted, save the file to your Windows “desktop” so that you can access it easily. Please save the file before running it – running from the website can cause file issues.
Double-click on the Game Advisor file and then click on the icon of the game you’re experiencing an issue with.
Click on the “Test Computer and Connection” button and please wait a few minutes while the process completes.
Once the process completes, a “Test Result” window will come up. This window will provide you with a link to update your ticket as well as tell you where the diagnostic report is saved. You can also view the report file.

Most likely the outcome will be: Contact your ISP
