Function.require error

[semaca]

Hello! I hope it's ok to post this here.
I have tried to install IbPro to my forum, the Arcade appears in the control panel, but I have an error:
Warning: FUNC::require(./arcade/lang/lang_arcade_enlang_Arcade_en.php) [function.FUNC-require]: failed to open stream: No such file or directory in /arcade/functions/functions.php on line 576

Fatal error: FUNC::require() [function.require]: Failed opening required './arcade/lang/lang_arcade_enlang_Arcade_en.php' (include_path='.:/php/includes:/usr/local/share/pear/') ....

How can i make it work? :erm:

maybe you messed with the both arcade.php files ?

one arcade.php must be in forum's root, the other in /admincp

verify if they are both in correct places :)
