CS Cart Beta 4 - 404 Page Errors

Hi all.

I was wondering if anyone else was having the problem after installing the beta 4 version of CS Cart. We keep getting [color=#ff0000]404 page errors - Page Not Found[/color] when we create a category and try going to the page. We also installed the demo data and get the same result when trying to go to a product page. Any feedback would be appreciated.

Thanks much!
