So I am really interested in playing Naruto Online on both my chromebook and phone, in order to play on my phone, from my understanding is, I need to reach lvl. 5 first on the browser and then get the activation code. However anytime I try to launch the game on the browser, because I can't download the mini client on chromebook, the loading screen is all black which I assume isn't how it's supposed to be, I have a strong wifi connection and have been having this problem for 2 days now, I also have the most recent version of adobe flash installed (I already checked just to make sure). If anyone has any help please comment.

Here is what it looks like
