Error messages in "Register" page. Because of Gravity Forms Directory plugin

Hi guys,

I have Gravity Forms installed along with the plugin "Gravity Forms Directory." It is perfect for my needs. (i.e. user fills out form. Form entries are displayed on a page in table format.)

Unfortunately, when I'm logged in, and click on "REGISTER" (http://www.fithappensla.com/gauntlet/register/ ) which is part of Membership, I get the below errors. It used to re-direct to http://www.fithappensla.com/gauntlet/account/ when logged in. Now, I get a blank page with the errors. When I disable "Gravity Forms Directory" it works, once again. Is there ANY way around this so I can keep "Directory?" (which is free and otherwise awesome). Or am I just SOOL? Thanks!
