CST doesn't work

Hi! I'm trying to use CST tool to customize the PUC. I've installed pentaho ce 4.5.0 and I've modified the mantlesettings.properties in this way:

# startup urls (each displays in its own tab)
num-startup-urls=1
startup-url-1=/pentaho/content/pentaho-cdf-dd/Render?solution=Demo&path=%2FNew+folder&file=Demo+Dashboard.wcdf
startup-name-1=DASHBOARD

I've modified the file cst-config.xml in this way:

<rule match="USER" pattern="false" value="joe">
<tab title="Dashboard">/pentaho/content/pentaho-cdf-dd/Render?solution=Demo&path=%2FNew+folder&file=Demo+Dashboard.wcdf</tab>
</rule>

Anyone can help me? I don't understand what's wrong.

Thanks
