How to set blog (with code plugin) viewable to everybody.

Probably some setting I am overlooking but here I go..

I have an plugin installed to link to my music albums created in MusicCollection with the code:

{showalbum 5126} 

This works fine if I am logged in as a supper user but not as I am logged in as a registered user, and I want it to display to everybody...
Plugin is set to: Access public
Also blog is set to: viewable by everybody

So what am I missing?

Thanks for the help..
