The solution reached me ;-) Nevertheless, the practice in such cases is to open a support ticket and attach the solution there.
Having that said - your solution uses the RadMenu Classic. Since the installation file that you have is one for the newer version of the controls, namely RadControls for ASP.NET AJAX, I assume that you want to use them...? The skinning of the controls is quite different - the elements differ in CSS class names, so skin files from one version cannot be used with the other. The Telerik Trainer shows development with the ASP.NET AJAX version - I have included a sample project (attached to this post) that you can refer to. Also, you can use the help topics on skin registration
and development of custom skins
to gain further insight on the skinning process.
