Links not working

I'm fairly certain I was completely successful in installing Grawlix, but the links to any page besides the index are broken lead to a Not Found page. I think it's a site root directory issue, but this sort of thing isn't my forte and I'd rather ask for help before getting more lost.
Things I've tried:
-Putting a / in the site root directory field on the settings page in the control panel
-Changing the site root directory field to /test, saving, and then changing it back to / (and saving)

If it helps, here's a little more info:

Thanks!
