Why am I unable to play? WTF is Invalid?!

[Melvine]

Sorry about the aggressive title but I just recently came back to this game only to find out that I can't play. I get this message when I click play 
"Invalid game client file. Please update the game client or reinstall.(10004" What is this? What does it mean and why is it here?! Please someone give me a solution. 

I really want to get back into this game.  I have reinstalled the game client but I still get this message.
