Like I said if your style does not conform to the vb4 standards then your navigation may not work can not say without seeing it but there is no service that is going to majically make something work how it is not suppose to work.
I can check your site for free as thats support. If I find your style is the culprit you may need to ask your style developer how things work different so you can make things work.
Just my thoughts here on this.
If you want a more accurate answer I would need a full admin login to look how you have things setup otherwise I am just guessing.
