Can't get to my arcade - Errors

I can't get to my arcade anymore. :-( Everytime I click the link, I get this error:

Warning: main(./arcade/functions/functions.php) [function.main]: failed to open stream: Permission denied in /arcade.php on line 149

Warning: main(./arcade/functions/functions.php) [function.main]: failed to open stream: Permission denied in /arcade.php on line 149

Fatal error: main() [function.require]: Failed opening required './arcade/functions/functions.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/myusername/public_html/mysite/arcade.php on line 149

(I edited the absolute path in this post for security reasons, we were just hacked on our last forum)

Could anyone please help?
