Hey, i just defaced your website, not crash your pc, if you want back to normal, just Replace index.php at www folder and please remove phpmyadmin.
I just try your WEBSITE security, not RYL SERVER.
If you secured your website/server and other, no one can hack your website.
And, For more secured, i think you should install Abyss webserver.
if you want, you can get here :
http://www.aprelium.com/download and install, then install php modules to support your ryl register page.
------------------------------
Last word, We only test your website security, Please remember that.
I would't defaced your website again if you secured your website and server.
Other note: I'm not interest on RYL Gaming/server ...
