I logged in on the website. I pressed play. It brought up that white box thing with the start button. I pressed the start button. It showed the box with Nao and a loading bar in the bottom right corner. The game opened. Before I get the Nexon or devCat logo, and before the page with "start game" and "exit" comes up, I get a message with a bunch of text that says the game isn't working (can't seem to copy it, sorry). It tells me it will log me out, and asks that I contact customer support. It copies the following message to the clipboard:

This has happened about six times. I have not attempted anything to fix it because I am not computer savvy in the slightest. I also apologize for any inarticulateness in describing the incident in this post. It is partially due to my lack of vocabulary useful for describing computery stuff in general as well as the mechanics of this game in particular.
