cck date field not available in views

It's not really difficult for me to use views,but when I want to change the date argument from updated date to my created cck date field (as shown around 14:20) my own created cck date field seems not available.

The only cck thing that seems to be there is the following
content: - value
content: - value2

However choosing either of these does not help!

I followed the instructions in the screencast at http://www.drupaltherapy.com/node/76 and I also tried with a view from scratch. In the scrrencast you can see that the fields should be exposed under there cck field-name.

I have no problems with creating a view using another date (e.g. creation date or last updated, or whatever date that always comes with any node.

Does anybody have a clue?

Drupal 6.9; PHP 5.2.3; Date 6.x-2.0; Views 6.x-2.3

Thanks!
