First you need to get Skinstudio setup if you havnt already.
Open Windowblinds config window and go to 'change how my applications look'...delete the default skinstudio exclusion if you see one and add your own exclusion for Skinstudio.exe
The default one dosnt work right and you dont want WB skinning Skinstudio while your working.It will show you your current classic colors tho so thats cool.
Next go to Skinstudio's menubar and drop down the tools menu and open the preferences dialog.Set your name and email etc...
Put photoshop as the first image editor.
Open Neutronium and go to file>save as>...enter the name you want for your WB.
Open your new WB and look at the info panel to the right.(section attributes)...if the author information etc... is wrong,put in your info and then save the skin.(file>save)
Now its YOUR skin
Go to tools again and windowblinds>normalize image file names.Apply the skin and see if it is still working.(apply button next to import)
You should be ready to start making your start menu.
