Urgent: TYPO3 Script Help: freeCssDropDownMenu - repost

Hi, we need some fast help with a TYPO3 Project. We installed the extension freeCssDropDownMenu, but it does not work as expected. [login to view URL] - The menue shows up, but there are no vertical submenue points (dropout). Main level and first sublevel should be shown - When you click on a menu point, the main parts disappear and only the sublevel is shown Following format should be shown: main1 main2 -> submenue point 1 main3 -> submenue point 1 main4 When you click on e.g. "main2" the menu should stay, but mark parent and submenue item as active (css class="active") See the attached files please. Please tell me when you could start? As sooner, the better ;-)
