Postnuke + G2 No Login

Sorry if this is the wrong place for this, but can't really find the right place.

I am running Postnuke .762 and tried embedding Gallery2. Everything works just fine outside of Postnuke. Problem I have inside is that there is no login for anyone. I only need a few people to have access, but it G2 does not seem to be getting permissions from Postnuke. I am assuming something is setup wrong.

I tried the Resynch Users and Groups which I thought might pull over the pn data into G2, but I get an error:
Error (ERROR_MISSING_OBJECT) : 3 GalleryGroup
in modules/core/classes/helpers/GalleryEntityHelper_simple.class at line 142 (gallerycoreapi::error)
in modules/core/classes/GalleryCoreApi.class at line 2424 (galleryentityhelper_simple::loadentitybyexternalid)
in /home/therealt/public_html/trgnet/modules/mGallery2/pnadmin.php at line 305 (gallerycoreapi::loadentitybyexternalid)
in /home/therealt/public_html/trgnet/includes/pnMod.php at line 735
in /home/therealt/public_html/trgnet/index.php at line 108

If I go back and try it again it says this:
You are not authorized to carry out this operation

It keeps giving me either the first or the second error. I don't even know if this is the button that will fix my login issue, but that is the only thing I see to try. Has anyone have an answer on why it is not recognizing me as having permissions to admin the gallery inside of pn? I have myself as admin on everything and i added Gallery as well just in case it needed to be specified. Help please....

Also, is there a way to get rid of the Register link at the top or will that go away when it recognizes users? Thanks for any help.
