Invalid Block Type Joomlart_Jmslideshow_Block_List

I’ve tried to install the JM Product Slider from the Ores Theme using the installation guide. When I add the Product Slider Block to the content of the home page, I get an Invalid Block Type Exception. How can I fix this?
Block Code:
{{block type=”joomlart_jmproductsslider/list” name=”jmproductsslider”}}
Stack Trace:
exception ‘Mage_Core_Exception’ with message ‘Invalid Block Type: Mage_Joomlart_Jmslideshow_Block_List’ in /var/www/virtual/b3rgmann/magento.b3rgmann.mensa.uberspace.de/app/Mage.php:595

#14 /var/www/virtual/…/index.php(87): Mage::run(”, ‘store’)

  1. OK, I've fixed the exception. The template app\design\frontend\default\jm_ores\layout\page.xml contains a block of type joomlart_jmslideshow/list.
    But my product slider is still empty and the format looks a little bit destroyed (have a look at http://magento.bergmann89.de)
