url SEO problem, the url is too long.

I installed the "SEO Script Generator (Extended)" (http://www.opencart.com/index.php?route ... order=DESC) on the newest OpenCart, it works fine, but there is a problem, let me set an example.

If I click the products on homepage, lets say the link is: http://www.domain.com/p-5300-andy-lau-a ... ttable-2cd (the first one is domain, the last one is for the product)

If I first click the category, then sub-category, then the product, the link added each time, and it becomes:
http://www.domain.com/c-3-chinese-music ... ttable-2cd
(the link consists of domain-category-subcategory-product) , the link is too long.

I donot know whether I put myself clearly, the SEO-ed url should not in this way, can anyone help me to check the code of the SEO Script Generator (Extended), and tell me how to fix it?

Thank you very much!

re-up, wondering if anybody can help on this. i'm using the SEO URL's that came with, and the url's are getting so long they get cut-off and don't work. any fixes besides renaming my categories and products?

well can you think of any other way an auto generator could handle it. The only thing it can do is use what you give it. I suppose it could just set an arbitrary point that it cuts off the name, but then you would probably end up with duplicates.
