cpg1.3.5 Coppermine Integration

Got trouble integrating PunBB with Coppermine.

I do have the latest 1.3.5 coppermine version and 1.2.10 PunBB version,

I did what everything according to the Oppermine documentation:

In the punbb.inc.php:

// ------------------------------------------------------------------------- //
// PunBB 1.1.5 Integration for Coppermine                                    //
// ------------------------------------------------------------------------- //
// Modify the values below according to your Board installation              //
// ------------------------------------------------------------------------- //

// URL of your punbb
$path = 'http://www.wakeskating.nl/punbb';

// local path to your punbb config file        <--------local path from the copermine dir or   from this file, now it
require_once('../punbb/config.php');                      is set from the coppermine directory to the root and then to
                                                                          the punbb directory
// punbb mod == cpg Admin ?
define('MOD_IS_ADMIN', FALSE);             <------ do i have to edit something here?

In  include/init.inc.php:

// define('UDB_INTEGRATION', 'punbb');    <--------- removed "//"

Created the redir.php and save it in the punbb directory.

I'm getting this error message:

Fatal error :
There was an error while processing a database query

What goes wrong?

I can wait for a stable 1.4 version but would be nice to fix it now, wanna go "on air" with an integrated gallery and board.

Who can help me.  (plz no links to other topics cause if've looked there but I'm getting cinfused with all the different versions)

Thanx.
