Hello ChaynLynx,
You may or may not be aware, but the EnB emu website recently suffered a hard drive crashed and nearly all of the web content was lost! Not to worry though, all the server development and such is safe, so the game will go on. In fact, the play server is running atm and you can log on if you have an account and correct client.
With that said, I just want to let you know that you do have an out-dated launcher. The current version is v1.8.9.0. I'm not sure where you could download the latest client, since the website is still in the process of rebuilding, but I'm sure someone more informed than me will post and let you know.
