Hi there, I've removed the password from your reply because these are public forums and it's a security risk to post a password publicly.
The site http://www.debrugvideo.nl is actually not hosted by us here at WordPress.com, it's a self-hosted WordPress installation running on the WordPress.org software.
To clear up any confusion, WordPress.com and WordPress.org are two different entities.
http://support.wordpress.com/com-vs-org/
You've reached support for the free sites hosted at WordPress.com.
If you've lost the password for your self-hosted site, you'll need to try one of these solutions:

If you need further assistance, WordPress.org has a complete support site for self-hosted/installed versions of WordPress at:

Best of luck to you!
