Installed but not working

I just finished installing this hack and everything seemed cool but when I click on arcade on my navbar i get:

Warning: FUNC::load_template(./arcade/skins/skin_global.php) [function.load-template]: failed to open stream: No such file or directory in /arcade/functions/functions.php on line 298

Warning: FUNC::load_template(./arcade/skins/skin_global.php) [function.load-template]: failed to open stream: No such file or directory in /arcade/functions/functions.php on line 298

Fatal error: FUNC::load_template() [function.require]: Failed opening required './arcade/skins/skin_global.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/nollywoo/public_html/arcade/functions/functions.php on line 298

Can somebody help me? i don't know what is wrong?
