Hi, I've just installed the K2 extension but I keep getting these errors right after the installation:


Notice: K2 Content Elements for Joom!Fish were not copied to the related folder, because Joom!Fish was not found on your sytem.
Installazione componente: eseguita correttamente







Thank you for installing K2 by JoomlaWorks, the powerful content component for Joomla! 1.5.

Please, anyone can help me with this?
Though it says that installation has been successful, whenever I try to add a User Group or any other item in the K2 Dashboard I keep getting one of those errors.
