Navigate will keep on loading, but never work.

When I first noticed the Navigate module I liked the idea very much, and decided I wanted it on my website. I installed it on a test server, on which it worked great. When everything seemed to work I installed it on my actual website, at another server (so different settings may be the problem). At first, it seemed to work. The widgets showed up on the site, I could expand everything, all without problems.

But then I noticed it keeps loading something, which it can't, no matter how long I wait. When I try to use the widget to search for something (anything), it won't let me. All other functions have the same problem, they show up, but can't be used. I decided to watch the help link, but it says the page can't be found.

I read the readme file again, carefully, which said you might need the jquery update module. So I installed that one, jquery was updated, but it still won't work. Multiple times I tried to reinstall Navigate (even emptying all things in the database about the navigate module once) but it just keeps giving the same problem.

I've been trying to figure out what the problem is, but I am currently unable to install a test site on my actual server, so I'm hoping there is something you guys know that could be the problem.

Thank you very much for any help you could give me.
