我如何使用下载的magento模块

I am trying to use the following magento module https://github.com/netz98/N98_LayoutHelper to remove account dashboard links. I copied the content of app over app on my ftp and updated the local.xml file with

<customer_account>
<reference name="customer_account_navigation">
    <action method="removeLink"><name>OAuth Customer Tokens</name></action>
    <action method="removeLink"><name>billing_agreements</name></action>
    <action method="removeLink"><name>recurring_profiles</name></action>
    <action method="removeLink"><name>downloadable_products</name></action>
</reference>
</customer_account>

but I get this error when accesing the my account page

  Invalid method Mage_Customer_Block_Account_Navigation::removeLink(Array
    (
    [0] => OAuth Customer Tokens
    )
    )

    Trace:
