Hi,

I have installed the cks package but when I Activate it on my blog site I got the following error (http://[MySharePointSite]/demo/blog/default.aspx):

An error occurred during the processing of /demo/blog/themes/default/theme.master. Value cannot be null.
Parameter name: value


I can find the Theme folder here: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES
And I can find the theme when I open SharePoint Designer.
