An error?

Im having just 1 more problem. Ive installed everything but maybe im missing something??
Heres my problem:When i go into group permissions or anything to do with the arcade this happens:
Warning: main(./arcade/functions/functions.php) [function.main]: failed to open stream: No such file or directory in /admincp/arcade.php on line 37

Warning: main(./arcade/functions/functions.php) [function.main]: failed to open stream: No such file or directory in /admincp/arcade.php on line 37

Fatal error: main() [function.require]: Failed opening required './arcade/functions/functions.php' (include_path='.:/usr/local/php5/pear') in /home/ssclanse/public_html/admincp/arcade.php on line 37

Im using VB version 3.6.8 patch level 2

Any help will be greatly appreciated,
Thanking you in advance,
