Two issues in Directory plugin

Hey there, please log in at http://productwhorestore.com

login: test
pass: testaccount

and then go to:

http://productwhorestore.com/product-review/make-up-for-ever-hd-microfinish-powder/

both the leave a comment and reviews buttons aren't going anywhere... any idea how to fix that?

Also, I've set up a popup using the Pop Up plugin, and I've used the login shortcodes from directory on it, but they won't go anywhere. I love where those buttons lead on the nav bar, how can I get that to work on the popup?

Followup question - is there any way to get the stuff that shows up when you click on the login / register buttons to show up in a popup box? Client would love the signin / registration process in a popup and I'm not sure how to do that.

Thanks!
