1.While client is updating, click "Cancel" button,
2. The message in the box is "The Update process is incomplete", while the message between the box and progressbar is "Completed"
3.user may confuse.
refer to the attached screenshot for more detail

Don't press the cancel button while updating, you have to update to play the game.

The game's maps, character, and other files aren't installed until you do the update process. So you will get an error unless you let it finish.

The messages are indeed a bit confusing and should IMO be fixed.
