Install is something wrong with my site

[tadisaus2]

Hello,
I am using the same db with my other site to install the script, but it is not working.
Here is what I did:
I created a db, then, used the sql to import the tables and data to this db.
Then, I modified the configuration file to match with my new server, but it seems not working. All images don't show up correctly.
Please look at my site:

http://www.usmatch.info/directory/

When you click on category, it does not work.
I have .htaccess there.

Thanks.

I checked your site and noticed strange thing. You have a lot of ROOT categories. please check your categories table and delete all ROOT records except one. It should have 0 for id field.
