Ok, having access to your live site helped a lot in understanding the issues:

1. Ogone IPNs never arrived to your site in the last days at least.
2. DirectLink authorizations Ogone-side not given.

We will now continue with PMs to help you troubleshoot, but you will probably need assistance from your hoster to get to the apache access and error logs to understand "1", and someone from Ogone could help you on "2", otherwise we would need to take a look there too.
