Hey peeps I had a little trouble opening the client and the read me wasn't very clear but for the slow people like me :X Here's a tiny bit more detailed on how to run it.
He gives you a rar file when you extract the original rar file (The one you got online) when you open the folder there's a few run files but don't run them just yet because
they will not work and will give a long error in the cmd window.
You take that rar file inside the folder and choose to extract it at the C drive. To do that just simply click on the hardrive that says C:/ after that just extract it there
It will take around 5 minutes or a little less. After than you can run it fine.
