error after upgrade: Classname Phaidon\PiwikModule\Block\OptOutBlock does not exist

[MrMontesa]

Hey,
I just tested @Guite new version of piwik on a fresh 1.4.4 install. Install works and I was able to configure Piwik.
But when accessing the blocks module I get the following error:
Classname Phaidon\PiwikModule\Block\OptOutBlock does not exist

Heres the stack trace:

in system/BlocksModule/Api/BlockFactoryApi.php at line 65   -
        }
        if (!class_exists($blockClassName)) {
            throw new \RuntimeException(sprintf('Classname %s does not exist.', $blockClassName));
        }
        if (!is_subclass_of($blockClassName, 'Zikula\BlocksModule\BlockHandlerInterface') && !is_subclass_of($blockClassName, 'Zikula_Controller_AbstractBlock')) {
            throw new \RuntimeException(sprintf('Block class %s must implement Zikula\BlocksModule\BlockHandlerInterface or be a subclass of Zikula_Controller_AbstractBlock.', $blockClassName));

As the erros is in BlocksModule not sure if this is Piwik or Core issue.
Let me know if I can be of any help.
Thanks
