Install Error 3.3

Hello, I tried to install Snapsis NavMenu 3.3 which I just purchased.  I logged in as Host (DNN 4.6 I believe) and used the Module Definitions screen to install a new module.  I received the following log entry.   I am new to DNN and am wondering what I am doing wrong with the failure message below. Thanks.

Thanks. I am having a problem getting the menu to fully work.  Maybe you can point me in the right direction? It is displaying as a bulleted list, but I cannot seem to get a vertical hover list with flyouts to work.  I figure that I must have some kind of problem with the CSS being read.  The test site is at http://vrarecycles.org.dnnmax.com/default.aspx.  The interior pages are still HouseMenu.  I put the these lines in the index.ascx file for my skin

<%@ Register TagPrefix="Snapsis" Namespace="Snapsis.DNN.Skins" Assembly = "Snapsis.DNN.NavMenu" %>

Also tried id=NavList

and the pasted the code below into my skin.css file

/***** Main menu *****/

/***** Snapsis menu *****/

.TabList {
    font-size:120%;
}

#nav ul {
    padding:0;

I have a skin.xml file and put in

Brilliant!  I can't believe I missed that.  Thanks.
