Client does not start

[Nek0. 0]

Hello, I just got some pretty clean files from the internet, I tested a couple of files before but they were all bugged so I decided to start from pretty much 0, so I got some clean files, and I found something called "martysama 4.6", downloaded installed everything but when I double click to open the client, nothing happens. To mention that I tested a couple of serverfiles before and the client that came with them worked witouth any problems, so it's deffinily something about the client, someone on other forums said it can be from .dlls but I don't know what to do, what dlls to change or to add or even how.

To mention x2: I even tried recompiling the launcher, still doesn't do nothing
