balticcreations,

Did you rename the three directories that need to be renamed? Renaming them to the name of your own custom template name? If you use a foreign language (other than English) then that one directory needs to be BOTH created/put in the directory tree of your foreign language and also renamed.

Did you open any of the files from the install package and resave them with a text editor? If so, which text editor did you use to resave them?

Did you receive ANY type of message when you ran the sql command (to insert the lightbox menu in admin)? Did you receive a 'success' message that sql statements were processed?
