The fact that nothing is being shown on vBookie.php might suggest that a required template isn't present in the database. The installer only add templates and phrases to the default style (he should if you have another style with the same id then it doesn't work for the default, too), and if you are using a style that's not based on the default you might find that the templates aren't picked up.

Try editing vbookie_install.php and changing "$styleid=$vboptions['styleid'];" (appears twice) to "$styleid=N;" where N is the styleid of your style.
